Feature request: happy frame polynomial #353

Closed vnp85 closed 1 month ago

vnp85 commented 1 month ago

Checked in 2.6.1 (release version)

Related to the problem described in #347 we can observe that some frames may yield the correct polynomial, even if the average goes severely off (due to the high activity and extended plages of the Sun). Flow: open a ser video in the Video Analyzer (frame debugger). Unchecking the lock polynomial, and switching from average to individual frames, scrolling around, especially at around the maximum disk size, one may be lucky enough to identify frames in which the detection is almost perfect, and the spectral lines are straight. Having the option to enforce such a particular polynomial as a global one (button: consider this frame/polynomial the master frame for this video) would be nice.

Clicking with the mouse may not be accurate enough and consistently yields a "polar cap" feature onto the Calcium Sun.
