      Description

      This is a ticket continued from PIPE2D-1582 and addresses the wavelength windows to inter/extrapolate PFS spectra to measure the HSC and Gaia broad-band fluxes for the focal plane fitting. The assumption here is that we first apply the 'master' flux calibration vector to pfsMerged so that we can ignore the discontinuities between the dichroics and telluric absorption lines.

          case 6: n is missing. Interpolate between b and m, and extrapolate m to n. Use G and Bp. The extrapolation to n is a bit scary, but G should be fine as the extrapolation covers a limited part of the G-band. It covers a significant fraction of Rp, and let' not use Rp.

          I hope my comments above are clear, but let me know, sogo.mineo . This is very complicated.

          Thank you, sogo.mineo for implementing this feature. I think the code works OK. The left figure is a medium-resolution Gaia visit and the calibration accuracy is similar to PS1 visits in low resolution (I am a little concerned about the overall normalization offset in pfsSingle, but most FLUXSTDs have low-S/N in this visit and I would not worry too much about it). The 2nd is medium-resolution PS1 and is again similar.
