The calculations are based on the LOLA elevation map LDEM_65S_240M and are described in [MAZARICOETAL2011]. The values are binary, indicating whether a pixel is in permanent shadow (1) or not (0). Note a scaling was applied to make the PSR visible when opening this file in regular image viewer software (e.g., Preview). This label describes two objects. The first is a JP2 file of the corresponding uncompressed .IMG file. A jpeg 2000 compression is used to render the image. The second is an auxiliary xml file that contains extensible markup language that is interpreted by GDAL readers (www.gdal.org).
