Description
This is a question but it might turn into a defect.
How does asap get its polnos from an SDFITS file?
This allows me to get at the table header and columns:
ASAP>import Data_Reduction.FITS.superasap as S
The first is a scantable with the table HDU atached. The procedure groups scans. ASAP>tab_1994_338, scan_groups, aves = \
S.report_Tid_SDFITS("1994/1994_338.fits",plot=True)
Whar ASAP thinks the polarization codes are: ASAP>tab_1994_338.getpolnos() asap>:(0,)
What the polarization codes are in the SDFITS table: ASAP>tab_1994_338.data.field('CRVAL4') asap>: array([-2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2, -2,
-2, -2, -2, -2, -2], dtype=int16)
ASAP>tab_1994_338.headerCTYPE4? asap>:'STOKES'
