[daip] Polarizations?

[Andreas Brunthaler]

Dear AIP,

we have made an observation with single polarization and 8 IFs. This 
observations were repeated several times with the same observe-file. In 
all cases except one the correlation was correct and the correlator job 
file contains the following entries:

!*----- Correlator Table -----*!
!table 'correlator'!
fftsize = 512  polar = NO   spect_avg = 2
    window = UNIFORM       !row!
!endtable!

!*----- Frequency Table -----*!
!table 'frequency'!
sample_rate = 16000000   bandwidth =  8000000   polar = NO  !* row 0 *!
    fft_enable = (1,YES ), (2,YES), (3,YES), (4,YES), (5,YES),
                 (6,YES), (7,YES), (8,YES)
    base_freq = (1,22020490000), (2,22045490000), (3,22107990000), 
(4,22207990000),
                (5,22370490000), (6,22420490000), (7,22457990000), 
(8,22470490000)
    net_side = (1,1), (2,1), (3,1), (4,1), (5,1), (6,1), (7,1), (8,1)
    polarization = (1,'L'), (2,'L'), (3,'L'), (4,'L'), (5,'L'),
                   (6,'L'), (7,'L'), (8,'L')    !row!
!endtable!

As a result we have in our UV-data file 8 IFs and 1 STOKES, as it should be:
AIPS 1: ----------------------------------------------------------------
AIPS 1: Type    Pixels   Coord value     at Pixel     Coord incr   Rotat
AIPS 1: COMPLEX      1   1.0000000E+00       1.00  1.0000000E+00    0.00
AIPS 1: STOKES       1  -2.0000000E+00       1.00 -1.0000000E+00    0.00
AIPS 1: FREQ       128   2.2020490E+10       0.75  6.2500000E+04    0.00
AIPS 1: IF           8   1.0000000E+00       1.00  1.0000000E+00    0.00




However, for one observation, the correlator job file contains the 
following entries:

!*----- Correlator Table -----*!
!table 'correlator'!
fftsize = 256  polar = YES  spect_avg = 1
    window = UNIFORM       !row!
!endtable!

!*----- Frequency Table -----*!
!table 'frequency'!
sample_rate = 16000000   bandwidth =  8000000   polar = YES  !* row 0 *!
    fft_enable = (1,YES ), (2,YES), (3,YES), (4,YES), (5,YES),
                 (6,YES), (7,YES), (8,YES)
    base_freq = (1,22020490000), (2,22020490000), (3,22107990000), 
(4,22107990000),
                (5,22045490000), (6,22045490000), (7,22207990000), 
(8,22207990000)
    net_side = (1,1), (2,1), (3,1), (4,1), (5,1), (6,1), (7,1), (8,1)
    polarization = (1,'L'), (2,' '), (3,'L'), (4,' '), (5,'L'),
                   (6,' '), (7,'L'), (8,' ')    !row!
!endtable!

Here we have a UV-data file with 4 IF and 4 Stokes:

AIPS 1: ----------------------------------------------------------------
AIPS 1: Type    Pixels   Coord value     at Pixel     Coord incr   Rotat
AIPS 1: COMPLEX      1   1.0000000E+00       1.00  1.0000000E+00    0.00
AIPS 1: STOKES       4  -2.0000000E+00       1.00 -1.0000000E+00    0.00
AIPS 1: FREQ       128   2.2020490E+10       1.00  6.2500000E+04    0.00
AIPS 1: IF           4   1.0000000E+00       1.00  1.0000000E+00    0.00

Is there any way to correct this in AIPS?
