The ISS second loop didnot close using the automated python script.  We also tried to close the loop manually with the steps described in alog 14291 but without any success. The loop rails each time we try to close it. From some prelimianry investigation, it looks like there is some problem with the electronics readout of the PDs. Attached is a plot showing all 8 PD signals of the ISS photodiode array.
