15th Feb 2024: Astro Pixel Processor 2.0.0-beta29 released - macOS native File Chooser, macOS CMD-Q fixed, read-only Fits on network fixed and other bug fixes
7th December 2023: added payment option Alipay to purchase Astro Pixel Processor from China, Hong Kong, Macau, Taiwan, Korea, Japan and other countries where Alipay is used.
Hi Mabula,
perhaps it already exists, but I could not find it: I would appreciate to have an ASCII-file export of the quality scores of all the subs in the processing. Such a file would allow me to analyse the set-up and to see if there is correlation between quality and regions or periods (both on a small and large scale). Preferably such a file would comprise (at least) of the following data:
- Date
- Time
- Temperature (if available from FITS header)
- Humidity (if available from FITS header)
- Pressure (if available from FITS header)
- Image coordinates in RA/DEC (this may vary due to dithering)
- Image coordinates in ALT/AZI
- Star count
- Star roundness (median?)
- FWHM (median?)
- Background level (ADU)
- Noise (ADU)
- Any other readily available quality indicator that I missed here...
- A field indicating whether or not the sub was rejected based on quality
Thanks in advance!

Hi Nicolàs @infinnity-deck,
There is no such option yet. I have added it to my todo list, but it will take some time before this can be implemented because of other higher priorities.
I think it is usefull idea though, so therefore I added it to my ToDo list.
For your information, the quality scores are a relative score, so you will need to treat it as such. A score of 1000 for a certain image scale can be a completely different score in terms of actual quality of the data, when compared to a score of 1000 for another image scale shot at another location with another telescope.... so for 1 single setup with the same equipment you can use it to deduct meaningfull information when you vary the exposure time for instance.

Hi Mabula,
thanks for your response, I am glad you like the idea and am willing to include it. That the quality figure is relative is fine for my application as I am always imaging using the same set-up. Besides, once implemented, I would also have the separate quality indicators as eccentricity and FWHM to my availability.
Hopefully you to-do list is not too long 😉 (but then I am not in a great hurry).
cheers,
Nicolàs
