Mar 28 2026 APP 2.0.0-beta40 will be released in 7 days.

It did take a long time to have the work finished on this and it  will have a major performance boost of 30-50% over 2.0.0-beta39 from calibration to integration. We extensively optimized many critical parts of APP. All has been tested to guarantee correct optimizations. Drizzle and image resampling is much faster for instance, those modules have been completely rewritten. Much less memory usage. LNC 2.0 will be released which works much better and faster than LNC in it's current state. And more, all will be added to the release notes in the coming weeks...

Update on the 2.0.0 release & the full manual

We are getting close to the 2.0.0 stable release and the full manual. The manual will soon become available on the website and also in PDF format. Both versions will be identical and once released, will start to follow the APP release cycle and thus will stay up-to-date to the latest APP version.

Once 2.0.0 is released, the price for APP will increase. Owner's license holders will not need to pay an upgrade fee to use 2.0.0, neither do Renter's license holders.

Hi all,
It seems that the reading mode is not taken into account when creating masters.
This field exists in the FITS headers but is not written in the created masters.

In the figure below, READOUTM can be "Low Conversation Gain" or "High Conversation gain". And APP does not differentiate between the 2 types of data.

How to deal with that?

I would write it to the file name for now, that is what I am doing. Or, settle on one mode. I have a OGMA AP26MC which is a IMX571 sensor. I did the full sensor analysis and found the differences slight enough that I just use HCG all the time, with the Extended full well depth setting.
