Limiting Magnitude Maps
Here we present the maps of TAUVEX limiting magnitudes, as a function of declination. These are monochromatic magnitudes at each filter effective wavelength, as defined in Appendix A in TAUVEX Observer's Manual
These maps present limiting magnitudes for S/N=5. The colour-code scale shows the limiting magnitude values assigned to the colour. There are two sets of images. One is the limiting magnitude per one TAUVEX scan (which changes with Dec.) and the other set is the limiting magnitude for a total of 5000s exposure. Since the range of values is large, 16 bits per pixel are used.
In the Table there are images for northern and southern declinations. The differences, however, are very minor. For each of these there are 8 files - two for each of the main filters and two for `maximum' and `minimum' straylight estimate (see details in Observational Windows and Limiting Magnitude Maps) document.
In all the maps half of the sky (2 pi steradians) is mapped to a circle with a radius of 400 pixels. This circle represents the orbit and the Sun light comes from the top. The pole is in `400.5' pixel, so it is in between two pixels and thus problems are avoided. Black regions represent unobservable areas, either due to the high straylight or due to the obscuration by the solar panels.
