UPDATE FROM MABULA

I have had a very rough 2 months unfortunately health wise. I was struck 3x in a row with bacterial infections. The second infection occurred  after a routine hospital checkup and I became very sick. I had to rest and take a lot of antibiotics. Once I was recovering and restarting work 1 month ago, I again became sick. The infection was not yet gone, so even more antibiotics and rest was needed. Needless to say, it took a lot of my energy and I needed a lot of rest.

 

Finally, the infection is really gone and my energy is coming back step-by-step now and I have started work again. I am terribly sorry to have kept you waiting for support. I will address all outstanding questions and e-mails step-by step and will be on the forum daily from today.

 

APP 2.0.0-beta47 will come soon as well, a lot of work was already completed before I became very ill, so the release is also nearly ready for you. Beta47 will be much faster actually. Many workflows will be more than 2x faster, mosaics can even be 10x faster than before because registration really received a major boost... all compared to beta46.  Before I release it, I will make sure that everything is working properly and then I will release it.

I have 45 subs for Luminance layer, and after integration (average, weight by quality, filter=sigma rejection (kappa low=6.0, kappa high=3.0) I'm still seeing multiple satellite trails. The subs are well-dithered.

What's the solution for removing satellite trails entirely? Tuning sigma rejection somehow?

@mseningmail-com The default settings in APP usually work very well. Have you tried leaving everything at their default values, including leaving "integrate" to "automatic" in tab 6, and see what the result is?

And what's the reason you're using sigma rejection? Have you tried winsorized or MAD rejection?

If all of that doesn't work then try lowering kappa high but be careful when doing so to avoid rejecting useful data as well.

None of that was enough to remove the satellites, so I just excluded the subs (about a quarter of them had satellite trails in them, some very bright).

You can tune the Sigma rejection which might help actually, the kappa high can be lowered to, for instance, 2.0. At some point going too low will harm your data, but it should help to get rid of the trails.

Lowering Kappa High to 2.0 did it! Thanks!
