Cal-G12

"There is a measure of photometric zeropoint, extinction, and color terms in each band vs water-vapor content and other atmospheric indicators on cloudless nights."

Prerequisites

  • Zeropoints and color terms for standards fields determined on all nights indicated as cloudless by RASICAM.
  • GPS water-vapor monitor (or other methods) producing data.

Procedure

  • Correlate zeropoints and color terms with atmospheric indicators, quantify any correlation.

Verdict

  • Do we see expected or other impacts?

Consequences

  • Significant effect will make it more important to have monitors online.
  • Impact on future careful calibration techniques.
  • No operational consequences for initial survey ops.
