Observercode in FITS header

I tried to send a spectrum to the AAVSO database, but I get the message that my observation code is not correct. I now notice that in the FITS header it says twice ',' behind the code. I use the BeSS function to send the observer code to the AVSO observer code. But I now notice that there are 2 comma's behind the code. Can this be changed ? In earlier versions of SPcAudace this appeared to work. I am now using version 5.0.

Hi Erik,

Nice to read you.
How are you?

I will look for a patch. Actually you can modify this header's keyword with the following commands:
buf1 load your_spectrum.fit
buf1 setkwd [list "OBSERVER" "BERB" string "Observer name" ""]
buf1 set bitpix float
buf1 save your_spectrum_updated.fit

Nevertheless, have in mind that AAVSO database dosen't strictly follows Bess fits file and many observers complain when posting spectra there.

Hi Benji,

Thanks for your reply !
all is fine with me, thanks, we do our best to stay healthy. Hope you ar in good health as well.

I tried the commands you're mentioned below:
buf1 load your_spectrum.fit
buf1 setkwd [list "OBSERVER" "BERB" string "Observer name" ""]
buf1 set bitpix float
buf1 save your_spectrum_updated.fit
with the commandline buf1 set bitpix float, i get an error that 'subcommand is missing'

as result , i get a very weird spectrum with only vertical lines. I checked the observername, and now it is correct, without the 2 comma's, but the spectrum is changed.

Hi,

Here his the correct command: buf1 bitpix float.
Although the spectrum you saved is now built with integer values. So put it to rubish. I hope you have a copy of the original.
This was why I named differently the output spectrum in my previous post.
