Hello,

There's a very strange behavior when I try to run aperture photometry on ztf image cutouts. (I was using 5.03.00 and just upgraded to 5.03.02)

The images open up just fine, and hovering the cursor around shows coordinates and pixel values and everything. But when I try to run aperture photometry, it gives me an error that there's no signal for it to centroid on, as if perhaps it can't read the pixel values or something similar. Also, If I de-select the centroid feature, it allows me to click around and also asks for the magnitudes of comparison stars, but it doesn't actually place any apertures. So for that, it almost seems as though it has trouble reading the coordinates of the files and maybe doesn't know where the apertures should go?

Let me know if this is something you've heard of before, or if perhaps there's something obvious that I'm missing.

Thank you,
Scott
