ICID 10 => DARK_LED_UNBINNED

Illumination:

  • Dark (background) measurements corresponding to unbinned LED measurements of ICID 11.

Purpose:

  • Unbinned dark (background) measurements corresponding to unbinned LED measurements.

Location:

  • Eclipse side of the orbit.

Usage:

  • From launch onwards, once per day.

Description:

Dark (background) measurements with the exact same instrument settings as the LED_UNBINNED light measurement of ICID 11. The dark (background) measurements are performed directly prior to the unbinned LED light measurements on the eclipse side of the orbit with the Sun Aperture Mechanism (SAM) closed and with the Folding Mirror Mechanism (FMM) in the position that blocks all Earth light. The dark (background) measurements are eventually used to correct the light measurements in the 0-1 data processing.
