2MASS 2nd Data Release Ophiuchus Extinction Map

<p><b>Description:</b><br /> 2MASS Extinciton maps. This map is made from the Second Incremental Data Release and is missing sections of the cloud, but the portions available are little changed in the final map (which is under construction). The data values are magnitudes of visual extinction (Av). </p> <p><b>Telescope:</b><br /> <a href="http://www.ipac.caltech.edu/2mass/">2MASS</a></p> <p><b>Status:</b><br /> Finished</p> <p><b>Sampling:</b><br /> N/A</p> <p><b>Areal Coverage:</b><br /> 10 5.6 Sq. degrees</p> <p><b>Map Center (Galactic):</b><br /> l = 354:16:45 <br /> b = +15:55:10</p> <p><b>Map Center (J2000):</b><br /> RA = 16:33:03 <br /> Dec = -24:10:23</p> <p><b>Comments on Resolution:</b><br /> The map is smoothed with a gaussian filter with FWHM = 3 arcminutes or two pixels, so each pixel is 1.5 arcminutes. </p>
