Question about passband LSST script

Support Data Products
#1

I want to ask you a question regarding one of the scripts you committed to the official repository. The script I am referring to is: tutorial-notebooks/DP1/200_Data_Products/204_Calibrations/204_4_Bandpasses.ipynb at main · lsst/tutorial-notebooks · GitHub

We are trying to clarify the convention used in the tables provided in the notebook. In particular, we would like to know whether the throughput distributions are expressed in terms of photon counts or energy, and which magnitude system is assumed (AB, ST, or VEGAMAG).

Could you please help us clarify these points?

Hi @LorenzoMonti, thanks for posting your question!

As explained in the Introduction of the 204.4 tutorial, the throughput shows the percentage of incident flux at the top of the atmosphere that is recorded by the detectors as a function of wavelength. Does this answer your question?
