Basic analysis using Gaia

"Gaia is an image display and analysis tool. It provides the usual facilities of image display tools, plus more astronomically useful ones such as aperture & optimal photometry, contouring, source detection, surface photometry, arbitrary region analysis, celestial coordinate readout, calibration and modification, grid overlays, blink comparison, defect patching and the ability to query on-line (WWW) catalogues."
