The problem with the warnings about the CQ tables is now fixed.
However, I am now encountering a problem when I try to run CVEL on the
file that was outputted by SPLAT: namely, CVEL does not shift the VLA
antenna. This problem does not occur when I run CVEL on the original
(non-SPLATed) file.
My task inputs are appended below

AIPS 1: CVEL Task to shift spectral line data to a given velocity
AIPS 1: Adverbs Values Comments
AIPS 1: ----------------------------------------------------------------
AIPS 1: INNAME 'BG118J' Input UV file name (name)
AIPS 1: INCLASS 'SPLAT' Input UV file name (class)
AIPS 1: INSEQ 2 Input UV file name (seq. #)
AIPS 1: INDISK 2 Input UV file disk unit #
AIPS 1: OUTNAME 'TST' Output UV file name (name)
AIPS 1: OUTCLASS 'CVEL' Output UV file name (class)
AIPS 1: OUTSEQ 2 Output UV file name (seq. #)
AIPS 1: OUTDISK 2 Output UV file disk unit #
AIPS 1: SOURCES 'BNKL-I' Source list to shift, other
AIPS 1: *rest ' ' sources will be passed
AIPS 1: unshifted. Ignored for
AIPS 1: single source files.
AIPS 1: '*' or ' ' => all;
AIPS 1: QUAL -1 Source qualifier to shift,
AIPS 1: Sources with other quals
AIPS 1: will be passed unshifted.
AIPS 1: -1 => no selection by qual
AIPS 1: TIMERANG *all 0 Time range to shift
AIPS 1: SELBAND -1 Bandwidth to select (kHz)
AIPS 1: SELFREQ -1 Frequency to select (MHz)
AIPS 1: FREQID -1 Freq. ID to select.
AIPS 1: SUBARRAY 0 Subarray, 0=>1
AIPS 1: FLAGVER -1 Flag table version
AIPS 1: DOBAND 1 If >0 apply bandpass cal.
AIPS 1: Method used depends on value
AIPS 1: of DOBAND (see HELP file).
AIPS 1: BPVER 2 Bandpass table version
AIPS 1: GAINUSE 8 CL table version which
AIPS 1: contains the time/antenna
AIPS 1: dependent frequency offsets.
AIPS 1: 0 => 1.
AIPS 1:
AIPS 1: APARMS(1:6) will define the
AIPS 1: velocity parameters needed
AIPS 1: for single source files. The
AIPS 1: parameters you define here
AIPS 1: will override any of those
AIPS 1: set with ALTDEF. If any of
AIPS 1: APARM(1)-(6) are set CVEL
AIPS 1: will assume all are set.
AIPS 1: These are ignored in the case
AIPS 1: of multi-source files, you
AIPS 1: should use SETJY for them.
AIPS 1: APARM *all 0 (1) => for single source file
AIPS 1: the velocity of a given
AIPS 1: pixel (m/s).
AIPS 1: (2) => the pixel to which
AIPS 1: APARM(1) refers.
AIPS 1: (3) defines the velocity type
AIPS 1: 0 => LSR, 1 => HELIO
AIPS 1: (4) the velocity definition:
AIPS 1: 0 => optical, 1 => radio
AIPS 1: (5) aparms 5 & 6 define the
AIPS 1: rest frequency of the
AIPS 1: line in Hz; the value
AIPS 1: used is the sum of
AIPS 1: APARM(5) + APARM(6).
AIPS 1: See helpfile.
AIPS 1: (7) 0 => VLBI data
AIPS 1: 1 => VLA/ATCA/LBA/ATLBA
AIPS 1: (8) if > 0 then do not print
AIPS 1: messages about large
AIPS 1: channel shifts, used if
AIPS 1: deliberately want a large
AIPS 1: shift.
AIPS 1: (9) 0 => not smooth spectra
AIPS 1: while shifting
AIPS 1: >0 => smooth AC spectra
AIPS 1: by Hanning
AIPS 1: >1 => smooth XC spectra
AIPS 1: by Hanning also
AIPS 1: BADDISK *all 0 Disks to avoid for scratch
