/* ** ** Swift/XRT hardness ratio for Mrk 501. ** Hardness ratio for this file has been calculated by splitting the data at 2.0 keV. ** ** Data taken from the automatic processing at http://www.swift.psu.edu/monitoring/ ** ** When using these data and results in publications, please reference M.C. Stroh & A.D. Falcone 2013, ApJS, 207, 28; arXiv: 1305.4949. ** ** Key: ** ** BinCenter - Center of time bin (MJD). ** BinHW - One-half of the full time bin size (days). ** FracExp - Conversion factor between bin size and observing time. ** Ratio - Source hardness ratio (2.0 - 10.0 keV)/(0.3 - 2.0 keV). ** This is also Rate2/Rate1 from the following columns. ** RatioError - 1 sigma error in the hardness ratio. ** Mode - 0 if in Windowed Timing (WT). ** 1 if in Photon Counting (PC). ** Rate1 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 0.3 - 2.0 keV band. ** RateError1 - 1 sigma error in source count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetRate1 - Background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetError1 - Error in the background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** Rate2 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 2.0 - 10.0 keV band. ** RateError2 - 1 sigma error in source count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetRate2 - Background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetError2 - Error in the background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** ** ** Upper limits have an error listed as -1.00000. ** */ BinCenter BinHW Ratio RatioError FracExp Mode Rate1 RateError1 NetRate1 NetError1 Rate1 RateError2 NetRate2 NetError2 56116.296709 0.000825 0.29441 0.02407 0.98246 0 5.49477 0.21348 4.81023 0.18690 1.61774 0.11636 1.41577 0.10185 56116.298347 0.000813 0.29753 0.02423 0.98577 0 5.50404 0.21533 4.81459 0.18835 1.63759 0.11697 1.43516 0.10249 56116.300080 0.000920 0.27893 0.02270 0.99686 0 5.12918 0.19524 4.47453 0.17031 1.43069 0.10292 1.25052 0.08996 56116.301894 0.000894 0.33528 0.02595 0.98382 0 5.08176 0.19643 4.44970 0.17198 1.70383 0.11424 1.49195 0.10002 56116.694823 0.000353 0.39341 0.06718 0.95082 0 6.48039 0.57999 2.26332 0.20055 2.54946 0.37078 0.84558 0.12245 56116.695694 0.000518 0.27876 0.04531 0.98324 0 6.75508 0.52039 2.00856 0.15473 1.88304 0.26951 0.56322 0.08060 56116.696687 0.000475 0.36369 0.06125 0.97561 0 5.64798 0.49388 1.69478 0.14819 2.05410 0.29567 0.61630 0.08871 56116.697639 0.000477 0.40215 0.06802 0.93333 0 5.39820 0.49379 1.60823 0.14710 2.17091 0.30884 0.64706 0.09205 56116.699036 0.000920 0.36979 0.04463 0.92453 0 5.86657 0.36527 1.75755 0.10942 2.16939 0.22433 0.65036 0.06725
