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.
Hello!
I got a question:
The lightpad I use to take flats is quite bright, so I have to use short exposure times for the flats. However, the images sometimes have a rolling shutter effect, probably due to the refresh rate of the light of the flat panel.
I wanted to ask how APP is treating those images that have these "outliers". Do I have to worry about incorrect flats, or can APP create a clean Masterflat still?

Hi Tobias @tobigh3,
In my experience, such a rolling shutter effect really must be avoided to start with if you want realiable results. If the lightpad is so bright, you better find a way to dim it, maybe wrap 2-3 with tshirts in front of it while making sure the thsirts are not wrinkled. That can help, I have done this myself in the past.
MasterFlats are created by not only integrating the flats. The flats are normalized first. The flat frames that are bad due to rolling shutter will be normalized to the correct ones, so that surely will give issues and I do not think that outlier rejection will solve that. One thing that you can try to do is not normalize the flats in 2)Calibrate, you can disable that. But to be clear, that is not a solution really, you need to normalize flats for best results. The masterflat without normalizing the flats might be better than the normalized masterflat with bad flats in there though...
