COR1 User's Guide - local subset

Back to the COR1 User's Guide.

The routine SCCINGEST is designed to help people maintain a local copy of a subset of the SECCHI data. This is useful, for example, when copying data to a laptop for off-line access.

The basic steps are as follows:

  1. Download the data into a temporary directory (which may contain subdirectories).
  2. Define the environment variable $SECCHI_LZ to point to the top of the directory tree that will contain the data.
  3. Run sccingest, DIRECTORY where DIRECTORY is the name of the temporary directory.

The SCCINGEST routine scans the DIRECTORY tree for FITS files, moves the files into their correct positions within the $SECCHI_LZ tree, and catalogs them within local summary files. The usual SECCHI software can then be used on these data.

For example, suppose that you had copied a bunch of SECCHI files to the temporary tree "c:\mytemp", and wanted to store them within your local archive "c:\secchidata". You would enter the following commands

IDL> setenv,'SECCHI_LZ=c:\secchidata'	;If not already done
IDL> sccingest, 'c:\mytemp'

These steps can be applied any number of times to add data to an existing local archive. It's best to keep the temporary and archive directories separate, otherwise you can end up with multiple summary entries for the same files, which lowers the efficiency.

VSO access

There are a couple of routines which allow one to retrieve SECCHI data through the Virtual Solar Observatory. The routine XSECCHI_VSO_INGEST is a widget program that allows one to search through the VSO catalog, and optionally download the FITS files. The routine SCCINGEST is called automatically. There's also a non widget version, SECCHI_VSO_INGEST.

Web access

Data are available online from NRL through the SECCHI Flight Images Database tool. There's also a short form for simpler queries.
