Hi Rick,

You can change the image display dimensions (drag the edges of the image display) to get rid of some of white space. The decam image is odd-shaped, so probably you'll probably be stick with some white space. Zooming in will of course fill the white space too, at the expense of losing sight of parts of the image. Any of those changes are just for display purposes and you can display any way you want and still get the same photometry. Of course adjusting the contrast by dragging the histogram pointers at the bottom will improve the contrast of the decam display.

OK thankyou for viewing them. I've updated AIJ to today's version. DECaLS looks like this:

image-decam-547225-S3.fits


Pan-STARRS looks OK now, but the coordinates work outside the picture i.e. on the white side margins. Is this normal?
