Astroquery: Add image cutout module to mast

[bsipocz]

Currently the cutout image services are not covered by the mast module, and already existing services (e.g. http://ps1images.stsci.edu/cgi-bin/ps1cutouts) are not planned to be covered in the near future (https://github.com/astropy/astroquery/issues/896#issuecomment-381201394).

So this new addition may be a good hack day project for a new contributor.

does this not serve the problem? https://astroquery.readthedocs.io/en/latest/mast/mast.html#cutouts

[keflavich]

It looks like that only covers TESS cutouts, i.e., cutouts for one specific mission. We need cutout tools for other archives too.

Can I work on this one as well?

[bsipocz]

Let's ask @ceb8 for updates, whether this is something they plan to implement at MAST or not.

[ceb8]

One of our next quarter priorities at MAST is to map out updating/expanding our cutout services, which will include putting them into Astroquery.

[akirahirohito]

Thanks for the reply @ceb8! I appreciate it.

[jt2553]

Was the cutout feature added to MAST and/or astroquery last quarter, or is it still in the works?

[ceb8]

@jt2553 Current status of new cutout services in MAST are:

• Astrocut (https://github.com/spacetelescope/astrocut) has been updated to perform more general cutouts on fits files
• The forthcoming MAST interface for deep fields will include cutout functionality that will be accessible via a RESTful API and Astroquery (the astroquery part will come later) for Hubble deep fields

There are no current plans to add astroquery access to the cgi style cutout APIs (http://ps1images.stsci.edu/cgi-bin/ps1cutouts and https://hla.stsci.edu/fitscutcgi_interface.html).
