I found that ANTAB (31DEC15 and 31DEC16) seems to sometimes ignore the last tsys measurement in its input file:

Using this calin:

!---------------------------------------------
GAIN GB ALTAZ DPFU=1.97,2.00 POLY=1,0 /
!
TSYS GB FT=1.0 TIMEOFF=0 INDEX= 'R1:8', 'L1:8' /
278 23:02.00  32.5 32.5
279 02:55.50  31.2 31.2
/
!-------------------------------------------

I get a TY table which is missing the day 279 value (both times are within scans etc),
although ANTAB reports that it read in 2 values in the messages.

However, using the calin below, identical to the first except for the addition of the "BR" section, I wind up with both TY values for GB and the value for BR - ie. no missing values....

!---------------------------------------------
GAIN GB ALTAZ DPFU=1.97,2.00 POLY=1,0 /
!
TSYS GB FT=1.0 TIMEOFF=0 INDEX= 'R1:8', 'L1:8' /
278 23:02.00  32.5 32.5
279 02:55.50  31.2 31.2
/
!
GAIN BR ALTAZ DPFU=1.97,2.00 POLY=1,0 /
!
TSYS BR FT=1.0 TIMEOFF=0 INDEX= 'R1:8', 'L1:8' /
278 23:02.00  32.5 32.5
/
