MegaCam Zeropoint History |
|
The MegaCam zeropoints are calculated for each run using elixir and the Q97 calibration fields. We provide a CSV, updated shortly after the run is complete and the data is distributed, which you can download here.
The old zeropoint plot (with no annotations) can be found here.
This is an interactive plot: you can pan and zoom around to view the data range you are interested in, and you can mouse over each point to get useful information (the camera run id, the queue run id, the filter name, and the zero point).
