SWEA Software Development

Last Updated 2007-10-25

Currently, SWEA 3D distributions are available. Some PAD's are available but not uniformly yet. Moments are still in progress.

First off, where the data files are located:
IMPACT Level 0: /disks/stereodata/l0
SWEA Level 1: /disks/stereodata/l1/{ahead,behind}/swea
SWEA prevalid Level 1: /disks/stereodata/l1_unvalidated/{ahead,behind}
SWEA PADs: /disks/stereodata/l1_unvalidated/sweapd

The software used to create Level 1 data from Level 0 is at:
/home/peters/stereo/decom/idl/level1/swea
or
http://sprg.ssl.berkeley.edu/impact/peters/level1_software/swea/

The software used for loading and using Level 1 data is at:
/home/peters/stereo/idl
or
http://stereo.ssl.berkeley.edu/stereo_idl/

The current state of affairs:
The meat of most everything is in the Level 0 -> Level 1 conversion. Here we convert from engineering units to scientific, etc.
Notable routines are the swea_21x.pro series. These take raw telemetry packets are unpack, apply geometric factors, etc.
Each deals with a different kind of telemetry packet:
swea_210.pro - SWEA 3D distribution
swea_211.pro - SWEA 3D distribution (burst mode)
swea_212.pro - SWEA onboard PAD
swea_213.pro - SWEA onboard moments
swea_215.pro - SWEA spectra product

In general, each of these routines expects to be passed a telemetry packet and spits out an IDL structure with the relevant data.

Right now, the SWEA 3D distribution (210) is the most robust. Others are at different levels of development. The next furthest along is the SWEA moments (213) which attempts to unpack the moments data and currently returns the data in engineering units.

Also, there are routines for creating PADs from the 3D distributions and MAG data. These are located in:
/home/peters/stereo/idl_test
These are very kludgy and need cleaning up. Also, the conversion to the solar wind frame has not beem implemented (remnants of unsuccessful attempts, however, are in that directory).

See the doc at: /home/peters/stereo/idl/swea_user_readme for info on the routines for loading and using the SWEA data in IDL.
