Hello
I write you this message to report a bug in your FITS header when shooting with Asiair.
Indeed, wcs data in the header have problem what can cause crash with some software using wcslib (the official library for wcs data).
First error:
The A_ORDER
, B_ORDER
, AP_ORDER
, and BP_ORDER
keyvalues should be integer. The header gives them floating-point values.
This can be checked with the tool wcsware:
wcsware -l -t Light_NGC6974_60.0s_Bin1_gain200_20210627-010859_19.3C_0088.fit
A_ORDER = 2. / Polynomial order, axis 1
Rejected (1), invalid keyvalue.
B_ORDER = 2. / Polynomial order, axis 2
Rejected (2), invalid keyvalue.
AP_ORDER= 2. / Inv polynomial order, axis 1
Rejected (3), invalid keyvalue.
BP_ORDER= 2. / Inv polynomial order, axis 2
Rejected (4), invalid keyvalue.
4 WCS keyrecords were rejected.
Another error, and this one causes the crash of Siril (that use wcslib):
IMAGEW
and IMAGEH
are also meant to be integer.
Please, could you fix these issues?
