improving HDF5 moment generation with ZYX cube #602

Open kswang1029 opened 4 years ago

kswang1029 commented 4 years ago

as a performance enhancement of the moment generator, when the input image is in the HDF5 format, ZXY cube should be used instead of the XYZ cube.

We may need a complete reimplementation, similar to the Z profiles and the flux density stat -- it's difficult to reuse casa's functions with custom data. But I have a general idea for creating an HDF5 image object which reads from the rotated dataset and using it with casacore (somehow) by specifying custom axes, slicers, etc.. If this is possible, we may be able to do the same for the Z profiles.
