As far as I know, there is no possibility to tell FITSFigure to load only a certain part of an image, e.g. by something like \r\n```f = pyfits.open('bigimage.fits')\r\nscidata = f[1].data\r\nfig = aplpy.FITSFigure(scidata[1:100, 1:100])```\r\nor the like. I don't know if it's possible, but it would be very helpful.","assignee":null,"id":2394749,"number":46,"pull_request":{"patch_url":null,"html_url":null,"diff_url":null},"labels":[],"title":"Feature request: load parts of FITS files","html_url":"https://github.com/aplpy/aplpy/issues/46","closed_at":null,"url":"https://api.github.com/repos/aplpy/aplpy/issues/46","milestone":null},"action":"opened"}
