How to select reference frames for LNC (Local Normalization Correction) or LN (Local Normalization)

@mxcoppell Hi Min,

In APP you can load your lights and calibration frames and then go to tab 3 and click "analyse stars". Once this is done you can check if the reference frame selected by APP is to your liking. If not, select the frame you want in the list of frames at the bottom of the APP window and click the "set reference" button at the top of tab 4. Then click the integrate" button at the bottom of tab 6.

HTH, Wouter

Thank you, Wouter. 

In fact, that's my common practice, especially when working with mosaic mode for the data set from the dual-scope setup. 

The question I posted is about selecting reference frame/frames for local normalization correct/local normalization to deal with the stray light situation. And, for local normalization, multiple reference frames could be selected for the LNC/LN in PixInsight. Just trying to see how to do this in APP. 

No worries, if this is not part of APP functions. We could always fall back to WBPP.

@mxcoppell Ahh yes I misunderstood. This indeed is not possible in APP.
