/* ** ** 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 59317.223380 0.000845 0.22991 0.01828 0.98630 0 6.88686 0.23760 5.99324 0.20677 1.58337 0.11346 1.37674 0.09864 59317.225058 0.000833 0.24641 0.01968 0.97569 0 6.63716 0.23662 5.76090 0.20534 1.63544 0.11688 1.41817 0.10135 59317.226727 0.000836 0.25633 0.02071 0.98616 0 6.27157 0.23045 5.42255 0.19922 1.60760 0.11567 1.39096 0.10006 59317.228362 0.000799 0.23708 0.01870 0.98551 0 7.21620 0.25151 6.22905 0.21706 1.71085 0.12108 1.47658 0.10449 59317.230029 0.000868 0.22741 0.01790 0.98000 0 6.88886 0.23411 5.98560 0.20342 1.56657 0.11123 1.36254 0.09674 59317.231745 0.000848 0.23155 0.01839 0.97952 0 6.98615 0.24045 6.03309 0.20763 1.61762 0.11578 1.39523 0.09985
