 Description   

It was found that integrations of calibrated flux standards disagree with broad-band fluxes in an unexpected way.
Calibration vectors proved to be wrong because of misuse of PfsFiberArraySet's *= operator.

This figure illustrates the problem. The flux-calibrated FLUXSTDs are too bright even at the field center.

 

After fixing the code, the field center is calibrated well. There is a global pattern and is a separate problem addressed in PIPE2D-1362.
