COR1 User's Guide - GSFC

Back to the COR1 User's Guide.

This page describes the SECCHI archive setup at the Goddard Space Flight Center, and how to configure your computer to access the data. There are two main sites to consider:

GSFC domain

The SECCHI data are exported (read-only) via NFS and Samba by the computer "gs671-hifi". Five NFS links are required on unix workstations:

  • /Volumes/sata_a -> /service/sata_a
  • /Volumes/sata_b -> /service/sata_b
  • /Volumes/sata_a1 -> /service/sata_a1
  • /Volumes/sata_b1 -> /service/sata_b1
  • /Volumes/sata_a2 -> /service/sata_a2
  • /Volumes/sata_b2 -> /service/sata_b2

It's very important that these appear under "/service" to make the logical links work correctly. (Microsoft Windows users should only need to mount the /Volumes/sata_b2/stereo2 filesystem, since the Samba server takes care of the logical links.)

Once the NFS links are established, one can define the following environment variables:

  • setenv SECCHI_LZ /service/sata_b2/stereo2/stereo/ins_data/secchi
  • setenv SECCHI_BKG /service/sata_b2/stereo2/stereo/backgrounds

The SECCHI_BKG environment variable also needs to be defined in one's IDL startup file to avoid being overridden by the SolarSoft startup script. If you don't already have an IDL startup file, simply create a file (e.g. idl_startup.pro) with the following line in it:

  • setenv,'SECCHI_BKG=/service/sata_b2/stereo2/stereo/backgrounds'

and then define the environment variable IDL_STARTUP to point to this file.

IMPACT, PLASTIC, and SWAVES data are also available under /service/sata_b2/stereo2/ins_data.

NASCOM domain

There are six NFS filesystems that one needs to consider:

  • soho-arch00:/vol/newstereo/stereo2 -> /service/stereo2
  • soho-arch00:/vol/newstereo/stereo3 -> /service/stereo3
  • soho-arch00:/vol/newstereo/stereo4 -> /service/stereo4
  • soho-arch00:/vol/stereo/stereo5 -> /service/stereo5
  • soho-arch00:/vol/secchia -> /service/stereo5/ins_data/secchi/L0/a
  • soho-arch01:/vol/secchib -> /service/stereo5/ins_data/secchi/L0/b

Note that the SECCHI volumes are mounted over the stereo5 mountpoint, and that the SECCHI-B data use a different server name.

Although there is a logical link from stereo2 to stereo5, having the mount points appear within /service as shown above is not so critical, since the SECCHI data are completely self contained. The environment variables can then be defined as

  • setenv SECCHI_LZ /service/stereo5/ins_data/secchi
  • setenv SECCHI_BKG /service/stereo3/stereo/software/backgrounds

The SECCHI_BKG environment variable should no longer be needed, since the files are also within the SSWDB tree. IMPACT, PLASTIC, and SWAVES data are available under /service/stereo2/ins_data.
