If I understand you correctly, then each datapoint (O,D,X,Y) represents one photon hitting a pixel(XY) of a detector (D) during an observation (O). And that pixel may be struck zero, one or many times during a given observation. If it is hit more than once, then there will be multiple, identical, (O.D.X.Y) datapoints in the dataset for that detector/observation pairing?
Is that correct?
