SAS3YLOG Catalog
This database is the Third Small Astronomy Satellite (SAS-3)
Y-Axis Pointed Observation Log. It identifies possible pointed observations
of celestial X-ray sources which were performed with the y-axis detectors of
the SAS-3 X-Ray Observatory. This log was compiled (by R. Kelley, P. Goetz
and L. Petro) from notes made at the time of the observations and it is
expected that it is neither complete nor fully accurate. Possible errors in
the log are (i) the misclassification of an observation as a pointed
observation when it was either a spinning or dither observation and (ii)
inaccuracy of the dates and times of the start and end of an observation. In
addition, as described in the HEASARC_Updates section, the HEASARC added some
additional information when creating this database. Further information about
the SAS-3 detectors and their fields of view can be found at:

Disclaimer: The HEASARC is aware of certain inconsistencies between the
Start_date, End_date, and Duration fields for a number of rows in this
database table. They appear to be errors present in the original table.
Except for one entry where the HEASARC corrected an error where there was a
near-certainty which parameter was incorrect (as noted in the
'HEASARC_Updates' section of this documentation), these inconsistencies have
been left as they were in the original table.
