/* ** ** 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 58222.095168 0.000414 0.14206 0.03399 0.97902 0 2.42024 0.20589 2.00623 0.17066 0.34383 0.07689 0.28619 0.06399 58222.096268 0.000686 0.10296 0.02451 0.94937 0 2.06469 0.14799 1.71334 0.12280 0.21259 0.04826 0.17570 0.03989 58222.097437 0.000483 0.11446 0.02871 0.97006 0 2.50128 0.19813 2.04648 0.16209 0.28630 0.06814 0.23415 0.05569 58222.098522 0.000602 0.11777 0.02721 0.98077 0 2.15270 0.16320 1.75962 0.13340 0.25352 0.05533 0.20623 0.04500 58222.099856 0.000732 0.08675 0.02054 0.98814 0 2.25346 0.15111 1.82745 0.12254 0.19548 0.04438 0.15813 0.03590 58222.101114 0.000527 0.15282 0.03591 0.97802 0 1.89741 0.16548 1.54624 0.13486 0.28996 0.06328 0.23635 0.05158 58222.102234 0.000593 0.08988 0.02133 0.99024 0 2.64700 0.18197 2.17133 0.14926 0.23792 0.05403 0.19475 0.04421 58222.103296 0.000469 0.13260 0.03158 0.97531 0 2.33998 0.19183 1.91631 0.15709 0.31027 0.06938 0.25359 0.05670 58222.104187 0.000422 0.17624 0.04274 0.96575 0 1.99066 0.18693 1.61671 0.15181 0.35084 0.07845 0.28416 0.06354 58222.105431 0.000822 0.10655 0.02125 0.97535 0 2.38069 0.14736 1.93079 0.11950 0.25367 0.04810 0.20588 0.03904
