    # Explanation of table headings 7-9:
  • Today: Todays source rate in units of mCrab (Significance in parentheses)
  • Yesterday: Yesterdays source rate in units of mCrab (Significance in parentheses)
  • Tenday: Average source rate over the last ten days (Significance in parentheses)
  • All of these are only posted if the significance is >= 2-sigma.

    * Explanation of last four table headings:

  • Mean: Mean source rate in units of mCrab
  • Peak: Peak source rate in units of mCrab (also requires >5-sigma significance)
  • Days: Number of days with >5-sigma source detection
  • Last Day: MJD of last 5-sigma detection (Days since last detection)
