Parallelise postage stamps #3

Open ajstewart opened 5 years ago

ajstewart commented 5 years ago

May be possible to produce these faster by parallelising the code, but may run into issues of an image attempting to be accessed at the same time. In addition to multiple versions of the same plot being loaded into memory.

This has been attempted but I could not get matplotlib to play nice when generating the plots in parallel. Text would sometimes appear misplaced or stretched, including the legend. I think the issue is rooted at savefig or something to do with how matplotlib adds text to the figure.

See examples below. For now on hold. Probably best to run multiple instances of the process at once to get through images.

Separate plotting script?

This will be possible when dropping aplpy and switching to matplotlib/astropy. A new postage stamp routine will probably be needed.
