Feedback on pyslitmask

[crawfordsm]

Feedback from Ros Skelton:

• could only run the command line version on astro
• I couldn’t copy and paste anything into the text boxes, which meant that if I wanted to put in a long target name or new centre coordinates I had to type them in by hand, for example.
• I have my own region file showing all my possible targets in different colours for different priorities, and could load that into ds9, but as soon as I clicked onto the slits or reference star tabs the ds9 window updated and removed my regions, so I had to keep reloading them.
• I had slit widths of 2 arcseconds as an additional column for all the galaxies in my catalogue, but that didn’t seem to load - the slit widths stayed the default 1.5 arcseconds.
• Even after clicking on optimize there were slit collsions, so the resulting mask wouldn’t be usable. It seemed to work when the position angle was zero.
• on trying to save, with ‘Write .rsmt file’ I got a segmentation error

And on trying ‘Create finder chart from current image’ I got a different error but it also crashed: writing xml... running finderchart tmprsmttmp.xml /home/ros/SALT/proposals/2015-1_phase2/frame-r-002379-6-0093.fits /home/ros/SALT/proposals/2015-1_phase2/finderchart_test WARNING: AstropyDeprecationWarning: The wcs_sky2pix function is deprecated and may be removed in a future version.

• iraf was being used instead of pyraf but it would be helpful to add information about how to start it from the command line (either via pyraf or a script)
• copy and pasting may be related to logging in remote from a mac to linux server.
• slitwidths is a bug and needs to be fixed
• region file is a feature request to add identify all the slits from a ds9 region file loaded into the ds9 or from the GUI
• optimization was broken and throwing an error
• seg fault was not reproducible

[crawfordsm]

• More information from the output of the optimization (like total weight)
• info or tool tip added to optimize page for y-spacing
