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.

BINARY FORMAT OF RPFITS

VIS data	SYSCAL data
(baseline > 0)	(baseline = -1)
param 1=u in m	0.0
param 2=v in m	0.0
param 3=w in m	0.0
param 4=baseline number	-1.0
param 5=UT in seconds	sc_ut: UT in seconds
param 6= flag (if present)	sc_ant
param 7= bin (if present)	sc_if
param 8=if_no (if present)	sc_q
param 9=sourceno (if present)	sc_srcno
param 10=intbase integration time	0.0
param 11=data_format	0
followed by nchan*npol*(real[,imag[,wt]])	followed by sc_ant*sc_q floats
