I have started collecting data with our Hi-Star detector. Gas pressure inside the detector is too low and that is why count is very low and I see mostly red pixels (1 or 2 count per trial) but still can collect some data. When I collect data I see a black(Blank) rectangular area at the left (about 50 pixel wide and 512 pixel lenght) from top to bottom which no pixel shows up in this area. It seems pattern circle is truncated by about 50 pixel from left. Anyone has such an experience and knows how to fix this?
