/* ** ** 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 56507.617515 0.000379 0.23555 0.03706 0.97710 0 3.90628 0.26919 3.31740 0.22857 0.92014 0.13014 0.78255 0.11067 56507.618340 0.000446 0.21820 0.03482 0.97403 0 3.49940 0.23371 2.99025 0.19969 0.76359 0.11065 0.65363 0.09470 56507.619237 0.000451 0.19845 0.03118 0.98718 0 3.82289 0.24770 3.23948 0.20986 0.75864 0.10859 0.64354 0.09211 56507.620096 0.000408 0.23744 0.03766 0.99291 0 3.52557 0.24729 2.99140 0.20981 0.83713 0.11910 0.71169 0.10125 56507.620947 0.000443 0.19994 0.03185 0.98693 0 3.79726 0.24408 3.23369 0.20785 0.75921 0.11067 0.64578 0.09414 56507.621798 0.000408 0.21430 0.03372 0.96454 0 4.00859 0.26215 3.40345 0.22257 0.85903 0.12296 0.72872 0.10431 56507.622628 0.000422 0.22328 0.03518 0.97945 0 3.70490 0.25045 3.12158 0.21100 0.82724 0.11772 0.69676 0.09913 56507.623447 0.000396 0.21612 0.03446 0.97810 0 3.95828 0.26340 3.38557 0.22529 0.85546 0.12395 0.73167 0.10601 56507.624240 0.000396 0.22424 0.03563 0.97080 0 3.88706 0.26113 3.30833 0.22224 0.87164 0.12552 0.74116 0.10673 56507.625030 0.000394 0.22855 0.03574 0.94853 0 4.00601 0.26729 3.40292 0.22704 0.91558 0.12949 0.77649 0.10981 56507.625803 0.000379 0.24944 0.03999 1.00000 0 3.60490 0.26031 3.03858 0.21939 0.89919 0.12871 0.75653 0.10829 56507.626726 0.000538 0.15788 0.02417 0.98925 0 4.02584 0.22748 3.43921 0.19433 0.63558 0.09043 0.54150 0.07704 56507.627692 0.000428 0.21167 0.03337 0.97297 0 3.80780 0.25117 3.25293 0.21455 0.80601 0.11539 0.68823 0.09851 56507.628517 0.000396 0.24106 0.03807 0.98540 0 3.59474 0.25267 3.07897 0.21641 0.86655 0.12255 0.74198 0.10493 56507.629321 0.000408 0.22731 0.03621 0.97872 0 3.68535 0.25087 3.14402 0.21401 0.83771 0.12065 0.71431 0.10287 56507.630140 0.000411 0.27173 0.03980 0.99296 0 3.64532 0.24779 3.12535 0.21245 0.99055 0.12852 0.84872 0.11012
