Running mangadap on MUSE datacube #114

Hi Kyle!
Spectra looks normal before and after the resampling (besides displacement
of emission lines because of the geometric sampling).
Looking at the SNR file, 'VARIANCE' is at order 6.40140241e+37 and 'SIGNAL'
-9.22337204e+18, so the SNR is negative.
I suspect I have a problem with the mask or the units for fluxes. Fluxes
are in 10**(-20)*erg/s/cm**2/Angstrom
I have tried to not convert to flux densities but it does not solve the
problem.
I'm masking NaN values but maybe that's too much as you suggest.
You can find the original file in the following link:

If it can be helpful we can set up a zoom chat.
Thanks,
Maria

That error should indicate that either none of the spaxels met the S/N
criteria or they're too highly masked. I looked at your implementation of
the MUSEDataCube class, and it looks fine to me. A couple questions for
you:
- Did you compare the spaxels in the file to those after the
resampling?
- Before the code faulted, did it write the "Reduction QA" reference
file? It should be in the common directory with name that's something
like *-SNR.fits.gz. You can use that to check the S/N measurements.
I'd like to help get this working. Maybe we can set up a time to chat over
zoom, or you can send me the file (via a Google Drive link or something
similar) and I can help debug.

Hi Maria, Thanks for sharing the file! I've been playing around with the (beautiful!) cube this morning. Here's a few things I would try:
Here's my edited version of your

Hello,
I'm trying to run the DAP on a MUSE datacube using DataCube class following the provided example for KCWI data but I'm getting a ValueError: No good spectra! when running the SPATIALLY BINNING SPECTRA module.
I'm running dap using the default plan
manga_dap -f ADP-2019-10-08T16-15-37-213.fits --cube_module muse MUSEDataCube --plan_module mangadap.config.analysisplan.AnalysisPlan -o dap
I'm attaching the file with the defined class, in case my error is coming from there.
muse.txt
If someone has trying this already and can point me out to the error I'd appreciate it. Thanks!
