Dear all,
First I would like to thank you for the awesome work you have done with indi/ekos/kstars.
I use mainly Indi and I am trying to implement (slowly) my own sequencer in python using pyindi and other python opensource packages. My medium term goal is to have a fully automated virtual observatory, and of course, the long term goal is to implement it with real hardware![;)]( ";)")
I am pretty happy with what I have now thanks to indi, but I would like to go further on the image processing side now. I really like the ccd_simulator that is implemented in Indi although I havent had the occasion to look at the code.
For now, it looks like, depending on the frameType (FRAME_DARK, FRAME_FLAT, FRAME_LIGHT), I got realistic images, in 16 bits, where the mean level, and noise level (white gaussian noise I guess ?) depends on the exposure time.
If this is trye, it is already truly awesome !
There are two things I would need to know:
-what is the noise model and what are its parameters for each images (I need to know the ground truth values)
-it is possible to see actual deep sky objects on the images that come from gsc package ?
I downloaded the gsc package, but it looks like it only contains star catalogs, and generates star images. This is great because it allows to play with astrometry engines.
But I would like to know if the appearance, signal/noise ratio and maximum visible magnitudes are influenced by some parameter that can be tweaked,
Thank you in advance for your help[.
