TGBT15A_915_120 (evening of Wed 30th ET)
Bottom line: The spectra look reasonable, and switched-power baselines look good. But in a pattern I cannot discern, the system temperatures are intermittently way off.
Here is a summary of system temperature as a function of software running, receiver and mode: TGBT15A_915_120.txt
It seems the correct system temperatures are ~30K for X-band, and ~18k for L-band - this makes good astronomical sense.
all "old, old" scans look correct.
Some "new manager" scans have an incorrect value of Tsys. But not always. This is the case for all banks / all polarizations (for every one I have checked), so for the "hybrid" scans, both old and new HPC software give the wrong answer.
The "new manager" scans are not always incorrect.
Scan 3, X-band mode 10, bad (corresponding old, old would be scan 31, but note integration times are different)
Scan 20, X-band mode 10, good
Scan 18, X-band mode 4, bad (corresponding old, old would be scan 29)
Scan 8, L-band mode 4, bad (corresponding old, old would be scan 40)
