Reconstructed images needed #399

Open beckynevin opened 6 years ago

beckynevin commented 6 years ago

I noticed that there's an extension for the SDSS imaging bands in the LOGCUBE files (this is not a true image, but is recreated from the data cube). However, these extensions are not accessible via Marvin.

Additionally, there's no current way to access the preimaging data using Marvin.

I was thinking it would be nice to have the option to compare the actual imaging files (.fits files, not just a .png cutout of the galaxy) side by side with the various data available already with Marvin.

I'm undertaking a project where I compare imaging to kinematics for galaxies in MaNGA and would love to see this capability.

Thanks!

Thanks for the report Becky. I agree doing that comparison (which I don't think we have systematically done) would be very informative.

Accessing the reconstructed images is possible if you have opened the data cube from a file, e.g.

cc = Cube('8485-1901')
cc.data['GIMG']

but right now there is no way of way to access them remotely. Brian, Brett, and I talked about this and there are a couple ways in which we could implement this, but requires a bit of thinking and adding it to our timeline.

Accessing the preimaging is easier to accomplish and I have created a separate issue, #401, to implement it.
