ASCA Processing File List

The following files are included on the tapes distributed to guest observers. Each file is linked to an example of that file.

Examples of FITS files have had their binary data removed. The example files are from the July 1993 observation of the Seyfert galaxy NGC 1068 (sequence 70011000). FITS files have had their binary data removed, and some files have been updated to better represent current processing. For a detailed history of the calibration files used, see the configuration history

An explanation of the file naming notation used here is available.
