Calibrate Clementine Hires images

Overview Parameters Example 1

Description

This program serves to calibrate most images from the Clementine Hires camera. It does so through the use of some constants based on offset and flat images based on filter type. There are six possible offsets, with the resultant change being anywhere between eight and fifty to the DN. There are four flat images, one for each of the four possible filters. Information for this program came from JGR Vol 108, A radiometric calibration for the Clementine Hires camera: Robinson, Malaret, White.

K value: KFROM


Description

This parameter is used to choose either a user entered K value or a previously set, calculated K value.

Type string
Default COMPUTED
Option List:
Option Brief Description
COMPUTED Compute a K value from MCP gain mode This option has the program use a known K value depending on the MCP gain and filter type, very few MCP gain mode IDs are supported. The K value is the absolute coefficient per wavelength and MCP gain state.

Exclusions

  • KVALUE
USER User input K value User chooses a K value and enters it into the system. This is more likely as very few MCP gain modes are supported.

Inclusions

  • KVALUE

K value: KVALUE


Description

The K value is the absolute coefficient per wavelength and MCP gain state. This is an average of several possible K values, the default should not be used when possible as it is an average.
