Standard 2 Spectra Display with Energy Selection

• Shows PCA counts vs energy channel, summed over all 5 detectors.
• Shows count rate binned in adjustable energy bands.
• Displays the ratios of different energy bands as a function of time.
• This display is updated every 16 seconds.

• At the top is a bar of options controls.
• The top panel of the display shows the spectrum, with different color bands representing the selected energy bands.
• Below that is a panel of boxes showing counts in each energy band, and to the right is a box labeled 'Adjust Color Bands', with which you can do just that.
• The bottom panel of the display shows the time history of the ratios of the selected energy bands.

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.]

• 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)]

• Raw [no correction applied]
• Corrected [gain and offset correction applied]

• 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]

• Start [start accumulating data]
• Stop [stop accumulating data, use for excluding occultation data]
• Clear [clears and restarts the integration]

• 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

• Total Counts [calculates total area under the curve in number of total counts]
• Counts/sec [show counts / second]
