SWAS

SWAS 8th Release Data

THE EIGHTH PUBLIC DATA RELEASE FOR THE SWAS MISSION

The eighth SWAS public data release consists of a complete set of SWAS data from mission day 0049 (the first day of usable science data) to mission day 1509. The SWAS mission defines mission day 0001 as November 01, 1998.

NEW ISSUES WITH DATA FILES IN THE EIGHTH RELEASE

The eighth data release was delayed after we discovered a bug in the data processing pipeline software where the leap year correction for the year 2000 was not properly taken into account. For SWAS mission days after February 28, 2000, the translation from running mission day to emphemeris dates was off by one day. The primary effect of this bug was incorrect velocity corrections for solar system targets. For most solar system objects observed by SWAS (and all fixed targets), an error of one day results in an insignificant difference in the velocity corrections. However, for three comets, the day-to-day changes in velocity were large enough to warrant reprocessing of the data in the corrected pipeline software and to re-release these data to the public.
