2A is 2 IFs with RR polarization.  1A would be 1 IF.  I suspect there is 
a 2AC mode (I do not have the list in front of me).

C                         1=cont,
C                         2=1A, 3=1B, 4=1C, 5=1D,
C                         6=2AB, 7=2AC, 8=2AD, 9=2BC, 10=2BD, 11=2CD,
C                        12=4, 13=PA, 14=PB,
C                        15=1A/C, 16=1B/C, 17=1C/C, 18=1D/C,
C                        19=2AC/C, 20=2BD/C,
C                        21=2A, 22=4A

is the comment from FILLM but there is no place there with a simple 
explanation.  I note for example that the 2AD mode can be "compatible" 
or not compatible (i,e. requiring 2 output files rather than 1).
