Cross-Talk Measurement

Data Taking:

• 1. Measurement can be performed under non-photometric conditions.

  2. Any very bright star will do.

     • E.g., Beta Aquarii, a V=2.91 G0 star at RA=21:31:33.5, DEC=-05:34:16 (J2000.0) is visible from CTIO throughout the PreCam Survey observing season (although better positioned later in the PreCam observing season).

     • Generally any star bright enough to be suitable pointing standard (say V less than about 3) would be suitable for this measurement.

  3. One observation per CCD per amp.

Data Analysis:

• 1. Generally not the responsibility of the observer.

  2. Analysis will be performed offline.

  3. Maybe we can use Jiangang Hao's cross-talk script?
