Apr 9 2026 APP 2.0.0-beta40 has been released !
It has a major performance boost of 30-50% over 2.0.0-beta39 from calibration to integration, for mosaics even faster! 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. Improved Outlier Rejection with LN 2.0 rejection. macOS CMD+A works now in file chooser ! And more, all will be added to the release notes in the coming hours...
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.
Hello
I've just made a sequence of dark frames for a new camera, so as to build a master dark library.
When processing dark frame, I get three output files:
- one master dark
- a bad pixel map BPMxxx
- a rejection map MDxxxx-rm
For further processing of light sequences , I must obviously keep master dark files associated with a given gain/temp/exposure set
My question is : should BPM and RM be kept to be further used? I'm afraid my BPM files have been partly lost or overwritten .
Thanks for the return
Hi Jean-Philippe @alpheratz06,
Thank you very much for your good question.
The BPM or Bad Pixel Map should be kept forr further use, just like a Master Dark Library where you have Master Darks for a certain gain and exposure and temperature. The Bad Pixel Map is essentially a defect map of your camera's sensor. If you create 1 good Bad Pixel Map, you can use it for more than 1 year on all your objects with great success, no need to keep creating BPMs for each object from new darks or your old MasterDarks 😉
The rejection map with the -rm postfix is just informative, to show you where outliers have been removed while stacking the darks to a masterdark 😉 That rejection-map can always be deleted once investigated if needed.
Let me know if this answers your questions 😉
