agree with the Psize parameter in the FITS header.
- OUTPUTS
None.
- COMMON BLOCKS
STCOMMN - Contains RESULT(20,10) where RESULT(i,LUN) =
0 - 121147 for consistency check, 1 - Unit for consistency,
2 - bitpix, 3 - naxis, 4 - groups (0 or 1), 5 - pcount,
6 - gcount, 7 - psize, 8 - data type as idl type code,
9 - bytes / record, 10 to 10+N-1 - dimension N,

- SIDE EFFECTS
The data are written into the next group.
