Halo in WFPC2 F1042M Images: The GIF image below shows the observed F1042M image on the left, a Tiny Tim model without the halo in the middle, and the observed-Tiny Tim subtraction on the right. The Tiny Tim software now includes the halo. Each image is 9.8" on a side and displayed with the same log stretch.
