 ====Cannot Connect to ROCDAQ1====
-You may sometimes run into the error "''ssh: connect to host rocdaq1.physics.isu.edu port 22: No route to host''" when attempting to ssh into rocdaq1. This usually means that the power to rocdaq1 (and possibly DAQ2 if in the same area as they are now (oct 2022) has been interrupted. This is easily noticed if you were in the middle of collecting data through CODA, and the RCGUI unexpectedly terminated and DAQ2 rebooted itself.

 The problem was the the TDC sopt pulse was too close to the 25 ns width limit.  I increased it to 40 ns and the problem went away.

 Fill in the '''***''' with whatever you want to name the object and change the '''Plot Title''' to your liking. 4096 is the number of channels in the ADC, which means the ''4096, 0, 4096'' arguments are present to create 4096 bins in x, ranging from a low 0 to a high of 4095. The following commands will create a histogram of ''ADC channel number v counts''.

 Scaling by the time factor causes ROOT to default to a different type of histogram, run the following command to re-plot your data with standard histogram format. The next command will redraw the histogram scaled by the time factor, creating an ''ADC channel number v count rate (Hz)'' histogram.
