The calculations are based on the LOLA elevation map LDEM_65N_240M and are described in [MAZARICOETAL2011]. The values are continuous between 0 (permanent shadow) and 1, and indicate the percentage of timesteps where each pixel was sunlit (by any fraction of the solar disc). Note a scaling was applied to fit the data in the INT16 value range. It also makes it 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).
