/* ** ** 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 56090.922562 0.000506 0.40495 0.03453 1.00000 0 6.22787 0.28432 5.56594 0.25411 2.52197 0.18164 2.25521 0.16241 56090.923658 0.000590 0.29137 0.02363 0.98529 0 7.57095 0.29063 6.80204 0.26111 2.20597 0.15763 1.98200 0.14163 56090.924862 0.000613 0.29959 0.02448 0.99057 0 7.02012 0.27569 6.30036 0.24742 2.10315 0.15067 1.88751 0.13522 56090.926092 0.000616 0.31107 0.02545 0.96714 0 6.89226 0.27214 6.18558 0.24424 2.14399 0.15359 1.92417 0.13785 56090.927267 0.000558 0.32903 0.02698 0.99482 0 7.07702 0.28928 6.35142 0.25962 2.32855 0.16554 2.08981 0.14856 56090.928366 0.000541 0.34404 0.02867 0.97861 0 6.98481 0.29270 6.26859 0.26269 2.40304 0.17306 2.15663 0.15531 56090.929474 0.000567 0.32780 0.02678 0.98980 0 7.06550 0.28660 6.31983 0.25636 2.31611 0.16424 2.07268 0.14697 56090.930623 0.000582 0.33947 0.02815 0.98010 0 6.60858 0.27381 5.93137 0.24575 2.24340 0.16114 2.01353 0.14463 56090.932269 0.001065 0.32128 0.01944 0.98641 0 7.01176 0.20895 6.27980 0.18714 2.25274 0.11861 2.01754 0.10622
