= SYSCAL Data Storage Formats =

The RPFITS data stores some extra information in the header, as keywords, and some in the visibility data stream, by marking it with baseline number -1.
For single dish data (baseline==0) the u,v,w variables are replaced with ra,dec,utc.

Note: [ftp://ftp.atnf.csiro.au/pub/software/rpfits/rpfits-2.17.tar.gz The RPFITS source code] includes a documentation file called
rpfits_syscal.def with most of this information, I've fixed up most discrepancies with that document.

calJy = counts per Jy calibration applied to the data
