Mars Express High Resolution Stereo Camera¶
High Resolution Stereo Camera (HRSC) has 9 different filters. Each has it’s own instrument id, as well as the main/”HEAD” camera composing those filters. There is also another “Super-Resolution Channel” (SRC) channel, making-up a total of 11 distinct sensors. It is very important to understand which code is needed when/where.
HRSC is a variable rate line scanner, and so does not maintain one exposure duration, but rather differing exposure durations per line. This information is stored within the individual records in the image data itself, with the the first 8 bytes making up the double presicion ephemeris time that the line exposure was started, and the next 4 bytes making up the float containing that line’s exposure duration.
The SRC channel is a high resolution framing sensor.
