/* ** ** 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 56873.913361 0.000367 0.36128 0.03019 0.99213 0 9.45259 0.40729 8.72473 0.37592 3.41507 0.24456 3.15198 0.22572 56873.914157 0.000428 0.31103 0.02571 1.00000 0 9.34184 0.37827 8.59371 0.34799 2.90562 0.20943 2.67156 0.19253 56873.914932 0.000347 0.38815 0.03290 0.99167 0 9.26952 0.41373 8.56027 0.38207 3.59794 0.25930 3.32261 0.23945 56873.915656 0.000376 0.34166 0.02841 0.99231 0 9.76263 0.40802 9.01672 0.37685 3.33546 0.23976 3.08057 0.22143 56873.916414 0.000382 0.35517 0.02957 1.00000 0 9.21948 0.39419 8.51390 0.36402 3.27449 0.23389 3.02388 0.21599 56873.917178 0.000382 0.34440 0.02869 1.00000 0 9.46537 0.39875 8.74142 0.36825 3.25987 0.23432 3.01056 0.21640 56873.917881 0.000321 0.39899 0.03409 1.00000 0 9.66835 0.44396 8.92795 0.40996 3.85754 0.27800 3.56207 0.25671 56873.918584 0.000382 0.34649 0.02888 0.96970 0 9.65183 0.40425 8.91524 0.37339 3.34427 0.24101 3.08899 0.22262 56873.919371 0.000405 0.31450 0.02579 0.99286 0 9.83640 0.39331 9.08514 0.36327 3.09350 0.22153 2.85719 0.20461 56873.920172 0.000396 0.29546 0.02392 0.99270 0 10.80251 0.42059 9.97752 0.38847 3.19168 0.22654 2.94788 0.20924 56873.920930 0.000362 0.34968 0.02955 0.99200 0 9.84069 0.41791 9.08949 0.38601 3.44111 0.25143 3.17839 0.23223 56873.921683 0.000391 0.34420 0.02862 0.99259 0 9.37582 0.39508 8.65949 0.36489 3.22712 0.23137 2.98057 0.21370 56873.922450 0.000376 0.34957 0.02923 0.99231 0 9.53819 0.40732 8.81256 0.37634 3.33430 0.23967 3.08057 0.22143 56873.923237 0.000411 0.31678 0.02613 0.99296 0 9.63181 0.38993 8.89736 0.36020 3.05119 0.21932 2.81839 0.20259 56873.924307 0.000660 0.34105 0.02173 0.98684 0 9.54027 0.30535 8.81386 0.28210 3.25373 0.17923 3.00598 0.16558
