Photon energy scale

[michael-pitt]

There is a discontinuity in the photon energy scale for reconstructed photons above 500 GeV in cards/CMS_PhaseII_200PU_Snowmass2021_v0.tcl#L2075:

(abs(eta) > 0.0 && abs(eta) <= 1.5) * (pt > 500.0 && pt <= 14000.0) * (1.000) +
...
(abs(eta) > 1.5 && abs(eta) <= 3.0) * (pt > 500.0 && pt <= 14000.0) * (1.278) +
...
(abs(eta) > 3.0 && abs(eta) <= 4.0) * (pt > 500.0 && pt <= 14000.0) * (1.000) +
...
(abs(eta) > 4.0 && abs(eta) <= 5.0) * (pt > 500.0 && pt <= 14000.0) * (1.000)  

For analysis using high pT photons, it might be better to set the energy scale for high PT photons to 1 in all pseudorapidity regions, otherwise, some artifacts in energy spectra are observed. Or is there a newer estimation of the photon energy scale fpr PhaseII?
