/* ** ** 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 55873.932480 0.000362 0.44756 0.03871 0.99200 0 7.85297 0.37467 7.10545 0.33900 3.51470 0.25360 3.17984 0.22944 55873.933189 0.000347 0.51452 0.04556 0.99167 0 7.10607 0.36711 6.45637 0.33354 3.65621 0.26292 3.32236 0.23891 55873.933909 0.000373 0.47482 0.04164 0.99225 0 7.24306 0.36063 6.50174 0.32369 3.43915 0.24832 3.08783 0.22297 55873.934610 0.000327 0.57862 0.05157 0.99115 0 6.83309 0.36965 6.21198 0.33605 3.95374 0.28004 3.59421 0.25457 55873.935347 0.000411 0.42182 0.03627 0.98592 0 7.34648 0.34362 6.67745 0.31232 3.09887 0.22360 2.81643 0.20322 55873.936132 0.000373 0.51462 0.04492 0.98413 0 6.83738 0.35164 6.16564 0.31706 3.51864 0.24820 3.17182 0.22372 55873.936867 0.000362 0.50642 0.04446 1.00000 0 6.98235 0.35830 6.31462 0.32403 3.53600 0.25192 3.19589 0.22769 55873.937616 0.000388 0.50613 0.04456 0.97761 0 6.65013 0.33768 5.96034 0.30268 3.36586 0.24208 3.01802 0.21703 55873.938409 0.000405 0.47452 0.04134 0.97857 0 6.76847 0.33277 6.07778 0.29880 3.21177 0.23095 2.88585 0.20752 55873.939210 0.000396 0.44151 0.03840 0.97002 0 7.48076 0.35773 6.68432 0.31962 3.30280 0.23993 2.95108 0.21438 55873.939966 0.000359 0.51164 0.04489 0.95968 0 7.31896 0.37294 6.53388 0.33293 3.74470 0.26747 3.34018 0.23858 55873.940724 0.000399 0.47887 0.04155 0.97101 0 6.90483 0.33952 6.21185 0.30539 3.30654 0.23636 2.97332 0.21255 55873.941464 0.000341 0.55425 0.04937 0.99153 0 6.84431 0.36412 6.11876 0.32551 3.79347 0.27098 3.39729 0.24266 55873.942153 0.000347 0.55534 0.04921 0.97500 0 6.92541 0.36448 6.15852 0.32412 3.84593 0.27422 3.42247 0.24403 55873.942888 0.000388 0.45140 0.03943 0.98507 0 7.41062 0.35926 6.57612 0.31879 3.34517 0.24305 2.97104 0.21583 55873.943687 0.000411 0.43737 0.03787 0.97887 0 7.20416 0.33950 6.45545 0.30420 3.15088 0.22891 2.82142 0.20496 55873.944615 0.000518 0.43359 0.03290 0.97266 0 7.52948 0.31201 6.72898 0.27883 3.26472 0.20751 2.91989 0.18562
