5) Normalize
Data normalization is performed.
We keep everything at default settings.
All your light frames will be normalized for lokation and dispersion relative to your reference frame. Which is the top frame in the file list.
APP wil
1) calculate normalization parameters,
2) then perform normalization and
3) then perform noise and SNR calculation on the normalized data.
Reported back by APP are the lokation (background) and dispersion values of your frames, and noise and SNR. You’ll see that your lights are very equal in illumination. If your lights would have somewhat different lokations and possible changing gradients, the reported values would deviate much more.
APP always normalizes the data range of your lights from 0 – 1 in 32bits floats. This enables APP to process, without problems, data of different data types. So 16bit and 32bit light frames, can be stacked without problems. They will all be normalised to the same data range.
