This notebook is an example to visualize a CANDELS mosaic image that is a single-extension FITS with the file size of 4.9 GB. The conclusion of this exercise is that I think Ginga can handle big mosaic natively as-is. I am not sure if this PR needs to be merged; I opened this so others can play around with this notebook on different machines and report back any problems. I did not notice any spikes in memory usage; I think the
memmap
helps a lot here.p.s. Similar conclusion for Ginga standalone GUI but I did not try using all the plugins on this data, just
