2MASS Final Perseus Extinction Map

<p><b>Description:</b><br /> Extinciton maps made from 2MASS and NICER (Near Infrared Extinction-method Revisited). This map is made from the final 2MASS data release and cover all of Perseus. The data values are magnitudes of visual extinction (Av). Consult the error map and stellar density map to identify any problematic regions (few in this map). Versions in galactic and equatorial coordinates are provided. The equatorial versions look less smooth, since they were regridded without re-orienta
ting pixels. FITS headers for all these files occasionally refuse to play nicely with certain programs, but all display correctly in something like DS9.
