Release Notes for sdfits Version 1.9 - Released on Wednesday, 3 October 2007

(See all sdfits release notes at Software Report Central.)

The organization of /home/sdfits has changed. The output products of the online sdfits daemon are now found in /home/sdfits/ project where project is the name of the project being filled. This includes the output fits files, index files, empty flag flag files and log file as well as associated files for use with Zpectrometer data.
sdfits now has limited support for the Zpectrometer. The output product closely resembles an sdfits file but further processing is necessary before it can be used as other spectral-line sdfits files can be used.
The online sdfits daemon now also fills Zpectrometer data in addition to Spectrometer and Spectral Processor data.

The polarization and feed information are not always correct for Ka receiver data. The data as filled is correct for the SIG=1 data. For the SIG=0 (reference) data the polarization and feed switch to the other polarization and feed. This will be fixed in the next release of sdfits.
Duplicate scans within the same project sessions still adversely affect the online sdfits filler. Each time a duplicate scan is seen, all occurrences of that scan number will be written to the online SDFITS file. This results in multiple copies of at least one of those scans (more if there is more than one duplication of the same scan number). This will be fixed in a future release of sdfits.
The frequency axis in scans observed with the LSFS procedure is wrong for all but the first integration.
Documentation of sdfits is incomplete. We plan on documenting exactly how sdfits translates the values found in the raw FITS files to the actual values written to the output SDFITS file. A draft version of this document is now available. sdfits
