ICID 26 => DARK_LED_STABILITY_BINNINGEIGHT

Illumination:

  • Dark (background) measurements corresponding to LED stability measurements (binning factor 8) of ICID 27.

Purpose:

  • Dark (background) measurements (binning factor 8) corresponding to LED stability measurements (binning factor 8).

Location:

  • Eclipse side of the orbit.

Usage:

  • From launch onwards, once per week, five times per month.

Description:

Dark (background) measurements with the exact same instrument settings as the LED_STABILITY_BINNINGEIGHT light measurement of ICID 27. The dark (background) measurements are performed directly prior to the LED stability 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.
