Coverage of M33 by Epoch

M33 has been imaged by the U42 camera on the 20-inch telescope between September and January annually since fall 2012. The following images show the coverage in each epoch (labeled by the year the imaging started). The green squares bound the area covered by each image and the cyan crosses are the locations of the survey targets.

The image under the overlays is a color composite mosaic of the BVR images taken by the survey in September 2016.

DS9 region files are also linked for download those files contain additional information about the area, orientation, filters, and dates of the images taken each year. The text identifying each region in the files contains a six digit date code (yymmdd), the internal code identifying the field center (one or two letters), and then a dash followed by the filter name. For example "120917 a-V" notes an image taken on September 17, 2016 in the V filter for region "a."
