Allow mosaicking of HDUs based on WCS #19

Closed eteq closed 10 years ago

eteq commented 11 years ago

This may be a lot of work, so feel free to consider this a "long-term" issue.

One of the useful features I'm accustom to in ds9 is the option of loading mosaic-style fits files. For example, multi-ccd instruments will often put each CCD in its own HDU with separate physical (pixel) WCS info. The idea is that you can then use the WCS info in each HDU to place the chips in the right place relative to each other.

One could also use the same functionality to mosaic two sky-coordinate WCSs on top of each other, although that might be more work given the reprojection that might be needed.

This is definitely something I want to support and it's not too far off--I did some primitive mosaicing with Ginga already for a use case we have here at Subaru and it seems to work fine. We have several such instruments.

Ginga now has a fairly primitive but usable Mosaic plugin. It mosaics images "inline" based on a user-specified FOV and taking the pointing from the first image dropped into the pane. Definitely needs some work, but is already usable for some quick look type applications.

Mosaic plugin needs polishing and testing, but basic functionality is there. Closing this issue.
