All Sky Median Near Infrared Colour Excess Extinction Maps

We have created several all sky AV maps based on 2MASS. They are available for download here. Due to the size of the files, they are presented in 10 degrees high galactic latitude strips (360 degrees long). For details on the extinction maps see our papers Rowles & Froebrich 2009, MNRAS, 395, 1640 (12MB) and Froebrich & Rowles 2010, MNRAS, 406, 1359. We also added an online query tool to search for extinction values in our maps.
