/* ** ** 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 59647.197684 0.000593 0.30916 0.02517 0.99024 0 7.06941 0.28200 6.38024 0.25449 2.18556 0.15510 1.97412 0.14007 59647.198801 0.000524 0.30884 0.02555 0.98895 0 7.83302 0.31592 7.12511 0.28739 2.41919 0.17470 2.20075 0.15891 59647.199889 0.000564 0.30071 0.02470 0.97949 0 7.57910 0.29952 6.87641 0.27173 2.27912 0.16408 2.06752 0.14884 59647.201008 0.000556 0.29670 0.02436 0.97917 0 7.74186 0.30247 7.06274 0.27594 2.29700 0.16586 2.09539 0.15131 59647.202212 0.000648 0.27609 0.02220 0.98661 0 7.16328 0.26843 6.53498 0.24489 1.97770 0.14068 1.80427 0.12834 59647.203561 0.000700 0.24448 0.01956 0.98347 0 7.49928 0.26454 6.82461 0.24074 1.83339 0.13164 1.66764 0.11975 59647.204993 0.000732 0.24092 0.01917 0.99209 0 7.24760 0.25459 6.61273 0.23228 1.74608 0.12469 1.59309 0.11376 59647.206330 0.000605 0.28751 0.02315 0.99043 0 7.40152 0.28190 6.73504 0.25650 2.12798 0.15099 1.93597 0.13737 59647.207967 0.001033 0.27086 0.01720 1.00000 0 7.26135 0.21429 6.61368 0.19518 1.96682 0.11060 1.79054 0.10068
