# I was forwarded the following list of interesting SC parameters, which I have filled in with the PCF_NAME of the corresponding entity in the MIB.
# Most likely you'll need to find the corresponding packet SPIDs via the MIB PLF in order to request them from EDDS; and be able to extract and calibrate the raw parameters from the packet, again according to the MIB.

# NPWD3021 A_LCL3_20 WDE-3 TM
# NPWD3521 A_LCL5_20 WDE-4 PWR TM
# These are all for PCDU-A, for equivalent PCDU-B parameters substitute NPWTxxxx.
# There are LCL status parameters as well, but frankly for simplicity I would probably just take the current, if the engineering value is within a few bits of zero then the LCL is off.
# NCFT55P0 SADE-A calibrated PY array position (deg)
# NCFT55U0 SADE-A calibrated MY array position (deg)
# And equivalently NCFT56U0 and NCFT56Y0 if we are ever using the SADE-B
# 4) APR temperature
# This is a difficult one. Attachments below, including the list of PCDU thermistors from Airbus. You take your chances with these. The external URP is at least at the correct end of the PCDU, but it's external. The internal ones are (as far as I can see now) not close to the APR end.
# So I am not an expert on the detailed behaviour of the APRs.
# You can look at power coming in to the APR (from the arrays), or power going out. I think probably the former is more interesting

# You have pairs of measurements being current and voltage. And you have nominal and redundant measurements on array 1, and nominal and redundant measurements on array 2.
# You can also get a sense of how hard the APR is working from the Main Error Amplifier voltage, NPWD5002. Diagram below.
# These are all for PCDU-A, for equivalent PCDU-B parameters substitute NPWTxxxx.
# Note that the APR is adapting its behaviour very fast. You only have a subsampling in TM.

# NPWD2516 A_LCL1_15 STR-1 TM Prime Star Tracker LCL current
# NPWD3015 A_LCL3_14 STR-2 TM Backup Star Tracker LCL current
# These are for PCDU-A, for equivalent PCDU-B parameters substitute NPWTxxxx.
# STR currents typically have a lot of jitter because photon integration is less power-intensive than detector readout. How you see this may be a bit weird, in that the PCDU sampling may happen to mostly miss the readout peak, or mostly sample it, and these sampling sync effects can potentially change based on artificial things like switchovers. There may also be some additional variation due to the thermo-electric cooler, when active. There are LCL status parameters as well, but frankly for simplicity I would probably just take the current, if the engineering value is within a few bits of zero then the LCL is off.
They are calibrated in degrees.
The frame used is a bit weird.
-90 deg elevation is pointing in the spacecraft XY plane (i.e. "spacecraft equatorial").
Imagine starting from the stowed position (and recall the HGA is mounted on the minus -Z panel, on the "bottom" of the Spacecraft).
There's a 90 deg rotation to deploy the antenna to a typical "equatorial" position.
Then zero elevation corresponds to pointing the beam in the direction of SC -X, and the elevation motor is upside down, so motor elevation is back to front wrt right-handed SC +Z rotation.
Azimuth is positive around -Z
