Is there a plugin support calculate each photon for normal experiment?

[Kke ake]

fermi_plug.C and photon_plug.C support many, but not enough. Is there an plugin support calculate each photon phase for general telescope experiment?

as if I have a telescope position (x, y, z) and a list of GPS clock data, example MJD 54000.0 54001.0 ... ... 54002.0

how could I use a ephemeris file ephemeris.par to calculate each photon's phase?

What coordinates are x,y,z in? Is that Earth-fixed, like ITRF, or ECI?

If you have code to barycenter your events, then photon_plug will do what you want. If not you might want to use PINT.
