/* ** ** 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 59048.021984 0.000475 0.23738 0.04837 0.95122 0 1.92833 0.17165 1.64787 0.14668 0.45774 0.08391 0.39101 0.07168 59048.023014 0.000556 0.27280 0.04366 0.98958 0 2.28110 0.17091 1.92877 0.14450 0.62229 0.08801 0.52719 0.07456 59048.023868 0.000298 0.17303 0.04324 0.98058 0 2.60918 0.24977 2.22941 0.21342 0.45148 0.10421 0.38575 0.08904 59048.024478 0.000312 0.18046 0.04412 0.98148 0 2.50595 0.24022 2.14149 0.20528 0.45222 0.10171 0.38646 0.08692 59048.025396 0.000605 0.27072 0.04335 0.99043 0 2.09173 0.15711 1.78750 0.13426 0.56628 0.08008 0.48390 0.06843 59048.026351 0.000350 0.17771 0.04452 0.98347 0 2.15619 0.20998 1.84234 0.17942 0.38318 0.08845 0.32741 0.07557 59048.027007 0.000307 0.20369 0.05017 0.98113 0 2.21325 0.22847 1.89132 0.19524 0.45082 0.10081 0.38526 0.08615 59048.027711 0.000396 0.17410 0.04114 0.96350 0 2.14240 0.19416 1.83063 0.16591 0.37299 0.08139 0.31871 0.06955 59048.028648 0.000541 0.28276 0.04602 0.97861 0 2.24719 0.17357 1.91407 0.14783 0.63542 0.09102 0.54132 0.07753 59048.029496 0.000307 0.17141 0.04163 0.99057 0 2.60494 0.24695 2.22615 0.21104 0.44651 0.09984 0.38159 0.08533 59048.030454 0.000645 0.21324 0.03330 0.98655 0 2.51036 0.16619 2.13167 0.14112 0.53530 0.07571 0.45530 0.06439 59048.031507 0.000408 0.19381 0.04007 0.97872 0 2.45421 0.20565 2.09726 0.17574 0.47565 0.08989 0.40647 0.07682
