These maps show the footprints of various wide area imaging surveys
(existing, under-way and planned) that will likely be of interest for
follow up studies of eROSITA sources. Also plotted are contours of
Galactic dust reddening and the predicted eRASS-8 survey coverage
(assuming a sun-pointing orientation).
Each of the following high resolution maps shows the coverage from a
different perspective (one hemisphere per map), plotted using a
Zenithal Equal Area projection. The first page of each pdf file shows
all wavebands, the second page only optical coverage, and the third
page only NIR. The same information is also given at lower resolution
in png format, one file per waveband set, which may be better for
displaying on a beamer.
In order to make these plots the footprint of each survey was first
converted to the SDSS 'mangle' polygon format (see
the mangle website
for details). The actual plotting was done
with gnuplot.
