Galvin # ContactID: spase://SMWG/Person/Antoinette.B.Galvin # Description: Stereo Plastic STB Suprathermal List # A description and the original list can be found at: # https://stereo-ssc.nascom.nasa.gov/data/ins_data/plastic/level3/Suprathermals/ # Data provided by the PLASTIC team at the University of New Hampshire is under NASA grant NNX15AU01G. # Suprathermal data provided here is courtesy of Josh Barry, Nick Lubinsky and Antoinette Galvin. # Intro # This data product contains a list of automatically identified suprathermal proton events measured on the # Wide Angle Partition without a Solid State Detector (WAP non-SSD) portion of the STEREO/PLASTIC instrument. # This list in conjunction with the IMPACT magnetic field information and PLASTIC solar wind data can aid a # user in identifying energetic proton events related to Stream Interaction Regions (SIRs), shocks, upstream events, # magnetospheric events, etc. For information on the WAP non-SSD portion of PLASTIC see below. # A thorough explanation of both PLASTIC and IMPACT can be found in [Galvin et al., 2008] and [Luhmann et al., 2007], respectively. # Instrument # The WAP non-SSD portion of the PLASTIC instrument is utilized in creating these event lists. # This non-sunward facing section has an 180degree in-ecliptic view and covers an energy range from 0.2 keV/q to 80keV/q, # Electro Static Analyzer (ESA) step 128 to 0. Early in the mission the WAP non-SSD portion of both spacecraft, # STEREO-Ahead (STA) and STEREO-Behind (STB), are ideal for detecting bow shock/magnetospheric ion events. # Event Definition # The energy spectrogram produced by summing the 10 min resolution Supra_no_E_Non-SSD_class_0 and # Supra_no_E_Non-SSD_class_1 matrix rate data1 (there are two classes allocated for protons on the WAP non-SSD # so we sum them together) allows for quick manual identification of suprathermal proton events. The top panel in Figure 1 # in https://stereo-ssc.nascom.nasa.gov/data/ins_data/plastic/level3/Suprathermals/READ_ME_PLASTIC_Suprathermals.pdf is an # example of an energy spectrogram showing suprathermal proton signatures (the sum of Supra_no_E_Non-SSD_class_0 and # Supra_no_E_Non-SSD_class_1 matrix rate data), while the lower panel shows |B|. # Plots similar to those shown in Figure 1 can be created using the PLASTIC public domain routine SPLAT (IDL). # The SPLAT software can be downloaded at http://stereo.sr.unh.edu/data/PLASTIC_Resources/index.htm. # Daily plots similar to those in Figure 1 can be found at http://fiji.sr.unh.edu/wap_bfield_public.html. # In the automated process to define events, we first define 3 bands in Energy/Charge (E/Q) covering the same number # of ESA steps (8 ESA Steps). The red horizontal bands in the top panel of Figure 1 depict these energy bands. # The upper, middle, and lower energy bands cover the E/Q range 59.0-42.2keV/q, 19.7-14.1keV/q, and 5.95-4.26keV/Q, respectively. # If the average of the number of events in a 10 min increment in any one of the three energy bands exceeds a trigger value, # the program identifies the start of an event period. The end of an event occurs when none of the three E/Q bands are triggered. # The triggering of events was adjusted as to match those defined by eye. # Explanation of Columns in the STEREO Suprathermal Proton Lists # Column 1 & 2 Start Date/Time & Stop Date/Time # These two columns indicate the start and stop of each event. The date/time format is YYYY:MM:DDTHH:MM:SS.000Z. # Column 3 Duration (min) # This column gives the duration of the event in minutes. # Column 4 & 5 Event Averaged SW @ STB (km/s) & Event STDEV of SW @ STB (km/s) # The first of these columns is the average solar wind speed measured by PLASTIC-B over the duration of an event. # The second column is the STandard DEViation (STDEV) of the solar wind speed measured by PLASTIC-B over the # duration of an event. If no solar wind velocity data is available then the average and STDEV solar wind velocity have fill values. # Column 6 STB-Earth Separation (Re) # This column gives the event average separation distance between the center of the Earth and the spacecraft in Earth radii. # Column 7 & 8 Event Averaged Linear Miss (Re) & Event STDEV Linear Miss (Re) # The first of these columns gives the average Linear Miss to the Earth’s center (a term introduced in [Desai et al., 2000]) # of an event. To produce the Linear Miss the 1 min magnetic field data is analyzed to determine the direction of the field # during an event. A straight line is then extended from the spacecraft in the direction of the measured magnetic field. # The shortest distance between the extension of the magnetic field and the Earth is then the Linear Miss. # The Linear Miss of all 1 min magnetic field vectors within an event are averaged to give the value in column 7. # The next column is the STDEV of the Linear Miss of events in an event time period. # If no magnetic field data is available then the average and STDEV Linear Miss have fill values. # Column 9 & 10 Overlap SIR & Overlap +/- 1 Day of SIR # Using the SIR event list provided at http://www-ssc.igpp.ucla.edu/forms/stereo/stereo_level_3.html, # using the criteria outlined in [Jian et al., 2006], we place the number of SIR time periods the event overlaps in column 10. # In column 10, we place the number of SIR time periods with a day added to the end time and a day subtracted from the # start time an event overlaps. If the suprathermal proton event time occurred outside the time range inspected for SIRs # then -1 is inserted in these two columns. The time range inspected for SIRs is located in the 4th row of the suprathermal # event lists header. This row also contains the date the SIR list, used in the program, was last updated. # Column 11 & 12 Overlap ICME & Overlap +/- 1 Day of ICME # Using the ICME event list provided at http://www-ssc.igpp.ucla.edu/forms/stereo/stereo_level_3.html, # we place the number of ICME time periods the event overlaps in column 11. In column 12, we place the number of ICME # time periods with a day added to the end time and a day subtracted from the start time an event overlaps. # If the suprathermal proton event time occurred outside the time range inspected for ICMEs then -1 is inserted in these two columns. # The time range inspected for ICMEs is 2006-12-14 to 2011-08-01. # The date of the ICME list used in the program was 2012-04-04. # Column 13 & 14 Overlap +/- 1 Day of Shock & Overlap +/- 1 Day of Shock # Using the Shock list provided at http://www-ssc.igpp.ucla.edu/forms/stereo/stereo_level_3.html, we place the number of # shocks time’s ± 1 hour an event overlaps in column 13. In column 14, we place the number of shock time’s ±1 day an event overlaps. # If the suprathermal proton event time occurred outside the time range inspected for shocks then -1 is inserted in these two columns. # The time range inspected for shocks is 2007-01-14 to 2011-08-01. # The date of the shock list used in the program was 2012-04-04. # Column 15 & 16 Overlap SEP & Overlap +/- 1 Day of SEP # Using the SEP event list provided at http://www- ssc.igpp.ucla.edu/forms/stereo/stereo_level_3.html, we place the # number of SEP time periods the event overlaps in column 11. In column 12, we place the number of SEP time periods # with a day added to the end time and a day subtracted from the start time an event overlaps. If the suprathermal # proton event time occurred outside the time range inspected for SEPs then -1 is inserted in these two columns. # The time range inspected for SEPs is 2011-06-10. # The date of the SEP list used in the program was not listed. # Column 18, 19, & 20 Hi Bin Triggered, Med Bin Triggered & Low Bin Triggered # These columns represent how many times each of the three E/Q bands is triggered within an event. # The ‘HiBinTrig’ column indicates how many times the 59.0-42.2keV/q band is triggered, ‘MedBinTrig’ column indicates # how many times the 19.7-14.1 keV/q band is triggered, and ‘LowBinTrig’ column indicates how many times the 5.95-4.26keV/q # band is triggered within an event. The 59.0-42.2keV/q band is excluded as a possible event trigger on STB # before 10-21-2007 due to high background. # These data are delivered to the public domain on a regular basis. # Efforts are made to include the latest known calibration and background determinations, # however, these are expected to undergo revision. We therefore suggest that users regularly return to this page, # and make sure to get the most recent revision. # If used in presentations or publications: # We strongly suggest that Dr. Lorna Ellis (Lorna.Ellis@unh.edu) be contacted # to ensure that you are working with the latest release. # Please acknowledge STEREO PLASTIC Investigation (A.B.
