Title: Error: Parsing EGAIN . . .
Post by: GordonH on 2019 December 12 12:22:34

I'm getting the following error message consistently:

"Error: Parsing EGAIN FITS keyword: Parsing 64-bit floating point expression ISO1600" (With a "^" under the "I" is ISO)

I'm using TheSkyX Camera add on to control my Canon 6D. TheSky is using the EGAIN keyword to store the ISO setting. I understand that PixInsight is expecting a numeric in this field and not text. My question, since everything seems to process OK what may be going wrong unseen?

This is an improper usage of the FITS keyword "EGAIN".

From FITS File Header Definition (from https://diffractionlimited.com/help/maximdl/FITS_File_Header_Definitions.htm ):

...
EGAIN – electronic gain in photoelectrons per ADU.
...
ISOSPEED – ISO camera setting, if camera uses ISO speeds.
...

Please ask Software Bisque for using the correct FITS keyword.

Yes, I understand its an improper use of the keyword. My question is what is or is not being calculated correctly because its missing>

As far as I know neither EGAIN nor ISO is evaluated by a PixInsight process. The processing should be performed correctly.
