ASCA Sequence 27001000 Event File Info

This page lists the filtered and unfiltered event files sorted by instrument and mode. Exposure times (not dead time corrected) and count rates are given for each file along with a list of FITS keywords describing the observation mode. Where two values are separated by a slash, the first value refers to the filtered event file and the second to the corresponding unfiltered file.

The following information is also available:
