Data Reduction Frequently Asked Questions
I want to process MOS data of the same target from different nights together - how can I do that?
The pipeline allow the user to stack several observations of the same target. However, if you want to process science data from different nights together you should limit the available calibrations to those from one night as the pipeline assumes that the calibration data were taken without mask movement in between. It is currently not possible to process data from several nights together with the closest-in-time calibrations associated to each science data.
