VTEST: Measures velocity discrepancy across fields
INNAME Input UV file name (name)
INCLASS Input UV file name (class)
INSEQ 0.0 9999.0 Input UV file name (seq. #)
INDISK 0.0 9.0 Input UV file disk unit #
CPARM Compute controls
(1-3) start,stop,incr RA
(4-6) start,stop,incr Dec
(7-9) start,stop,incr UT
DPARM More controls
(1-3) start,stop,incr day #
(4) Year (0 -> 1997)
(5) Field size (degrees)
(6) > 0 -> use earth centered
ignore AN file
(7) > 0 max over UT and Day
<= 0 max over RA and Dec
Task: Test range of LSR and heliocentric velocities in DPARM(5) degree
images maximized over a range of RAs and Decs for specific UTs
and dates. The uv data set is used solely to provide an AN file
to define the coordinates of the telescope.
INNAME.....Input UV file name (name). Standard defaults.
INCLASS....Input UV file name (class). Standard defaults.
INSEQ......Input UV file name (seq. #). 0 => highest.
INDISK.....Disk drive # of input UV file. 0 => any.
(1-3) Start, stop, increment in RA - degrees
0's => 0, 350, 10
(4-6) Start, stop, increment in dec - degrees
0's => -30, 85, 5
(7-9) Start, stop, increment in UT - hours
0's => 0, 23, 6
(1-3) Start, stop, increment day # - day in year
0's => 0, 350, 30
(4) Year number (< 1950 => 1997)
(5) Field size in degrees - position differences
are done as DPARM(5)/2 in ra and dec
0 => 2.
(6) If > 0, ignore the uv file and take the antenna
coordinates to be 0. This means an Earth-centered
system such as is used for VLBI.
(7) > 0 => find max velocity differences over UTs and day
numbers for each Ra and Dec
<= 0 => find max velocity differences over RAs and Decs
for each UT and day number
