Shows PCA counts vs energy channel, summed over all 5 detectors.
Sample plot of std2spectrum

At the top is a bar of options controls.
Options buttons:

File:

  • Freeze [to stop scrolling of data, select again to resume.]
  • Save or E-mail File [Allows you to email an ascii dump or postscript plot to yourself.
  • Quit [quits the window.]
Layer:
  • All [default, shows sum of all three layers of all 5 PCUs.]
  • Sub.3 [shows sum of all 5 PCUs: {(layer 1 + layer 2) - 2 x layer 3} for each detector (approximates background subtraction)]
Combine:
  • Raw [no correction applied]
  • Corrected [gain and offset correction applied]
Display:
  • Live [clear data between each partition]
  • Integ(rated) [accumulate data]
  • LateData [pop up a window when data is late]
  • Strip Chart [show late data graphically]
Integration:
  • Start [start accumulating data]
  • Stop [stop accumulating data, use for excluding occultation data]
  • Clear [clears and restarts the integration]
Axis:
  • X-axis:
    • min [zoom in as far as possible]
    • zoom [zoom in closer]
    • ZOOM [zoom out]
    • MAX [default, maximum data range]
  • Y-axis:
    • Linear
    • Log
Statistics:
  • Total Counts [calculates total area under the curve in number of total counts]
  • Counts/sec [show counts / second]
