Fits headers - AA5 default?

[Forum_2014]

I usually need to supply much more than the basic fits header data to allow submission of spectra to the BeSS database.
If I edit the fits header file in one image, is it possible to "pick up" on this data as a default for all subsequent images???

There is not a direct command, but you can do it with a script.

Fabio,
Generally the same location and equipment are used over extended periods, it's only the target object which changes.
There are three areas:
1 Object
OBJNAME
otherwise
-RA
-DEC
-EQUINOX
-RADECSYS
2 Acquisition
DATE-OBS
EXPTIME
BSS_INST
otherwise
-TELESCOP
-DETNAM
-INSTRUME
BSS_SITE
otherwise
-BSS_LAT
-BSS_LONG
-BSS_ELEV
OBSERVER
CRVAL1
CDELT1
CRPIX1
CUNIT1
CTYPE1

3 Processing
BSS_VHEL
BSS_TELL
BSS_COSM
BSS_NORM

The full details of the various fields are given in "Specifications of spectra eligible for BeSS"

Maybe a script which writes these keys to the current image is enough(?)

Code: Select all

BSS_VHEL = -10.5
BSS_TELL = "none"
BSS_NORM = "corrected"

sub WriteBessKeys()
  Image.SetKey("BSS_VHEL",BSS_VHEL)
  Image.SetKey("BSS_TELL",BSS_TELL)
  Image.SetKey("BSS_NORM",BSS_NORM)
end sub

WriteBessKeys()

Otherwise the could be read from the current image and written to all the other ones opened in the Astroart desktop.

Fabio,
Hmmmm
Thanks for that.
Let me see what I can do.
