atlas#

atlas is a Python GUI for viewing FITS images, in the spirit of SAOImage DS9.

It opens files into frames, shows them singly or tiled, and lets you read individual pixel counts straight off the image. Everything beyond the image itself is a tool you switch on, so a default launch stays a plain viewer rather than a wall of panels.
