A test run was conducted on the PDFR system last afternoon and transimpedance plots were generated for 6 of the PDs. The laser was shut down after the test run.
I have not verified (yet) if the transimpedance values indicated by the plots are correct or not. The values mostly look INCORRECT. But the peaks are exactly where they need to be. *phew!*
Reasons: Incorrect calibration, Light other than from the PDFR system fibers on the PDs
Will have to work on debugging all this.
