Looks like a busy time - the Photon Transfer sequences are interesting, I'll ask some Q's as to what that's about. With a healthy rover, Conjunction must be frustrating. Safe, low data volume, but time consuming sequences are all good

About PCDB, I have not found any meaning from Google Search engine. In fact, it has many meanings. I imagine it might refer to an database where the information is kept.

Changing the theme, about the photon transfer, I searched it and I think I have not concluded it except it might be narrowed down:

Hence, conservation of momentum requires that at least two photons are created, with zero net momentum. The energy of the two photons—or, equivalently, their frequency—may be determined from conservation of four-momentum. Seen another way, the photon can be considered as its own antiparticle. The reverse process, pair production, is the dominant mechanism by which high-energy photons such as gamma rays lose energy while passing through matter.

The classical formulae for the energy and momentum of electromagnetic radiation can be re-expressed in terms of photon events. For example, the pressure of electromagnetic radiation on an object derives from the transfer of photon momentum per unit time and unit area to that object, since pressure is force per unit area and force is the change in momentum per unit time.

about the photon transfer...

Photon transfer is a technique to compute the gain and noise of a camera system from multiple images at different signal levels, originally developed by Jim Janesick when he was at JPL.
