Zeroing nanslices #16

Open jbrinchmann opened 1 year ago

jbrinchmann commented 1 year ago

In some situations, we create MUSE cubes that have all NaN slices. This is particularly the case with fixed OUTPUT_WCS situations. This proposed change, adds a zero_nan_slices option to process and Zap which is set to True by default and which sets any slice that is filled with NaNs will be set to zeros. This is identical to how the laser gaps are treated.

After cleaning the NaNs are reinserted, again just as for the laser gaps.

Do note that this is now on by default - if not, these cubes are not possible to process so this does not really break any backwards compatability.
