History
The level 1B PDS data files have been processed to have north up and east to the right. This processing is removed during the import of the data into ISIS. If the level 1B file is missing lines, the program will add lines of data containing the special pixel value NULL to pad the image to the correct number of lines. The location of missing lines is determined by looking for time differences between adjacent records of the UTC_TIME table greater than the exposture duration.
Chandrayaan-1 M3 L1B PDS data products consist of:
The level 0 PDS data files were not flipped or mirrored from the orientation they were in when collected. The level 0 files are missing the same lines as the level 1B files, but they do not contain the necessary information to add NULL lines as do the level 1B products.
Chandrayaan-1 M3 L0 PDS data products consist of:
Name | Description |
---|---|
FROM | Input detached PDS formatted Chandrayaan-1 M3 label file |
TO | Output calibrated spectral radiance image cube |
LOC | Optional output file containing lunar surface location of all radiance image pixels. |
OBS | Optional output file containing observation geometry information for all radiance image pixels. |
This file is a detached PDS formatted label which contains pointers to the following files:
Type | filename |
---|---|
File Mode | input |
Filter | *.LBL |
Output ISIS cube containing calibrated spectral radiance pixels (units of W/m^2/µm/sr) or level 0 raw data.
Type | cube |

Filter | *.cub |
This is an optional output file containing location information for the center of all pixels contained in the radiance image file (L1B) created from the "TO" parameter. The output ISIS cube will 3 band containing the following:
Type | cube |

Internal Default | None |
Filter | *.cub |
This is an optional output file containing observation geometry information for each pixel in the radiance image. The output ISIS cube with have ten bands containing the following:
Type | cube |
