Seventh SWAS Public Data Release

The seventh 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 1326. Mission day 0001 is defined as November 01, 1998.

The SWAS service now provides a link to a "5-panel plot", generated by SWAS operation center. In JPEG-format, the "5-panel plot" shows a cummulative (grand) spectral co-addition for the nominal center position (offsets of 0'', 0'' in RA and Dec) of the target. In a few cases a non-zero offset position was used due to the lack of data at the nominal center position. The plot includes informative statistics: target position, offsets, local velocity as measured with [CI], and integration time per spectral channel.

The observations made for Comet/1999 T1 (McNaught-Hartley) during SWAS mission days 824 - 886 have been reprocessed. This was necessary because a newer ephemeris which yielded more accurate radial velocities was made available after the initial processing was completed in the SWAS pipeline software system in 2001. The processing of the spectra in the 7th public release is based on the ephemeris for C/1999 T1 generated on 2003 March 4th, using the web-based form available at http://ssd.jpl.nasa.gov/cgi-bin/eph.

• (a) As was pointed out by the folks at the IRSA for the 3rd public data release, there seems to be a problem with duplicate entries in the FITS-format archive where individual positions of several sources appear to have duplicate, identical grand co-adds for each spectra line (in other words, the line spectra are 725x2 in dimension instead of 725x1). This appears to be an IRAF problem. The SWAS-Science Operations Center (SWAS-SOC) will try to correct this problem in the final archive release for the mission which will occur in September 2004.

 

• As with public data release #3, the SWAS Science Operations Center has chosen not to provide FITS-format grand co-add files for moving targets/time-variable targets at this time. Such a grand co-add would be misleading and confusing to archive users. The SWAS SOC recommends that archive users work with the Class-format files for these targets.

SWAS targets are identified by the science team internally using nomenclature that often conveys information about the nature of the observation as well as abbreviations of more standard naming schemes in order to accommodate the limited number characters that can be used for target names in the source database.

Although the SWAS naming scheme does not follow any formal astronomical nomenclature standards, most target names are easily recognizable without explanation. Source names that may cause confusion are given below:
