Specify Source Extraction
From https://trello.com/b/fRzpTfHn/sourceextraction . Source Extraction is currently under-specified in the design.
Goal: specify the software (recipe and algorithm) to do source detection and extraction (detector position & counts).
We require in ESO Imaging Pipeline:
-
source extraction
- position: 0.01 pixel systematic error, S/N limited measurement accuracy
- counts: 0.2% systematic error, S/N limited measurement accuracy
-
background estimation
- 1e-3 (1e-4 is goal) systematic error (!!??)
-
PSF estimation
- no requirement
