/* ** ** 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 59708.090764 0.000521 0.27725 0.02252 0.98333 0 8.99332 0.33883 8.06045 0.30364 2.49342 0.17941 2.23179 0.16059 59708.091881 0.000596 0.24642 0.01980 0.98544 0 8.78457 0.31452 7.89136 0.28253 2.16465 0.15576 1.94595 0.14002 59708.093039 0.000561 0.28014 0.02240 0.97938 0 8.45459 0.31532 7.55559 0.28177 2.36846 0.16755 2.11437 0.14957 59708.094144 0.000544 0.27665 0.02259 0.97872 0 8.56491 0.32353 7.72328 0.29174 2.36951 0.17150 2.13667 0.15465 59708.095255 0.000567 0.26901 0.02169 0.98980 0 8.54128 0.31790 7.60180 0.28292 2.29769 0.16436 2.04591 0.14636 59708.096415 0.000593 0.24698 0.01984 0.98537 0 8.78087 0.31357 7.91793 0.28276 2.16871 0.15605 1.95558 0.14072 59708.097521 0.000512 0.28665 0.02327 0.99435 0 8.74842 0.33595 7.86634 0.30205 2.50775 0.17940 2.25516 0.16133 59708.098568 0.000535 0.26932 0.02199 0.98919 0 8.88726 0.33189 7.95473 0.29706 2.39355 0.17375 2.14321 0.15558 59708.099645 0.000541 0.28277 0.02299 0.98930 0 8.45133 0.32296 7.57095 0.28928 2.38980 0.17146 2.14036 0.15356 59708.100767 0.000582 0.22791 0.01817 0.99502 0 9.64399 0.33113 8.67245 0.29777 2.19797 0.15815 1.97514 0.14212
