extension |
I4B |
IN |
(0 based) extension number in which to write data. default:0.
If set to 0 (or not set) a new file is written from scratch.
If set to a value
larger than 1, the corresponding extension is added or
updated, as long as all previous extensions already exist.
All extensions of the same file should use the same Nside,
Order and Coord |
polarisaton |
I4B |
IN |
if set to a non zero value, specifies that file will contain the I, Q and U polarisation
Stokes parameter in extensions 0, 1 and 2 respectively, and sets the
FITS header keywords accordingly. If not set, the keywords found in header will prevail. |

Note: the information relative to Nside, Order and Coord has to be
given, either thru these keyword or via the FITS Header. |
