ShadowCam raw data are stored as 8-bit ISIS cubes. The instrument's 12-bit output is companded into 8-bit values and interleaved by channel into two memory banks. The raw product deinterleaves the data so each row is in the correct pixel order, but otherwise, it retains the raw 8-bit values without any calibration. The detector has six channels, each handling a 512-pixel section of the detector, totaling 3,072 pixels.

Each raw product comes with three ancillary products to help view or evaluate the data without downloading or processing the original file.

Browse Image - scaled-down image with the largest dimension of 1,000 pixels in PNG format.
Full-resolution COG - pyramidal product in TIFF format complying with the Cloud Optimized GeoTIFF (COG) standard without the geographic header to allow fast browsing via web-based tools.
Histogram - CSV-formatted histogram data with a bin for each 8-bit DN.

ShadowCam Raw data products have the following file names:

tnnnnnnnnnse(_***).ext

where:

t = target

M = Moon

E = Earth

C = non-Moon calibration

S = star

nnnnnnnnn = an approximate mission elapsed time (MET) in seconds

S = ShadowCam product

E = raw product

*** = ancillary product type

browse = Browse Image in png format

cog = Full-resolution COG - pyramidal product in TIFF format

hist = CSV-formatted histogram data

ext = the file extension

cub = ISIS cube files

png = browse image files

tif = COG - pyramidal product files

csv = text files

xml= PDS4 XML labels
