/* ** ** 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 59340.193240 0.000648 0.24900 0.02003 0.96875 0 8.19984 0.29230 7.30203 0.26029 2.04173 0.14726 1.81761 0.13109 59340.194574 0.000686 0.24010 0.01920 0.96624 0 8.04989 0.27997 7.22708 0.25133 1.93274 0.13913 1.73532 0.12492 59340.195986 0.000726 0.23878 0.01899 0.98008 0 7.56825 0.26472 6.76157 0.23650 1.80717 0.12906 1.61604 0.11540 59340.197300 0.000587 0.27046 0.02182 0.97044 0 8.28929 0.30722 7.44056 0.27576 2.24194 0.16063 2.01271 0.14420 59340.198550 0.000663 0.25450 0.02040 0.99127 0 7.71858 0.27976 6.89230 0.24978 1.96436 0.14040 1.75554 0.12546 59340.199815 0.000602 0.27508 0.02238 0.99038 0 7.77791 0.29278 6.96472 0.26217 2.13958 0.15431 1.91467 0.13809 59340.201021 0.000605 0.26986 0.02199 0.98086 0 8.06820 0.30154 7.14327 0.26694 2.17730 0.15767 1.92363 0.13929 59340.202549 0.000923 0.24916 0.01677 0.99060 0 7.96548 0.24149 7.10553 0.21541 1.98466 0.11924 1.77157 0.10643
