Flux Calibration for Extended Sources and Cut-outs

Science Alerts & Brokers
#1

Hello everyone,

I have a few questions regarding flux calibrations performed by LSST, specifically:

  1. Does the current LSST flux calibration work well for extended sources?
  2. Is flux calibration already applied to cut-out images?
  3. Does LSST provide a standard first-level calibration, such as a direct conversion from counts to flux (e.g., x counts = y Jy)?

Any clarification or further details on how flux calibration is handled for these specific use cases would be greatly appreciated!

Thanks in advance for your help!
