/* ** ** 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 58021.503265 0.000399 0.13266 0.03158 0.96377 0 2.65999 0.21694 2.25263 0.18371 0.35287 0.07891 0.30125 0.06736 58021.503977 0.000312 0.19276 0.04615 0.98148 0 2.42641 0.23884 2.06955 0.20369 0.46771 0.10207 0.39689 0.08661 58021.504582 0.000292 0.18223 0.04448 1.00000 0 2.53101 0.24757 2.17592 0.21284 0.46123 0.10313 0.39670 0.08870 58021.505256 0.000382 0.13953 0.03382 0.96970 0 2.58149 0.21958 2.21313 0.18825 0.36020 0.08176 0.30896 0.07011 58021.506063 0.000425 0.11623 0.02786 0.97959 0 2.75903 0.21292 2.35127 0.18144 0.32070 0.07277 0.27463 0.06232 58021.506810 0.000321 0.17178 0.04163 0.97297 0 2.52108 0.23561 2.15994 0.20184 0.43306 0.09684 0.37099 0.08296 58021.507606 0.000475 0.09893 0.02459 0.98780 0 2.75753 0.20287 2.36449 0.17395 0.27281 0.06477 0.23449 0.05568 58021.508468 0.000388 0.17709 0.03855 0.97761 0 2.55190 0.21561 2.20060 0.18593 0.45192 0.09067 0.38967 0.07818 58021.509168 0.000312 0.15207 0.03663 0.98148 0 2.89925 0.25982 2.47770 0.22205 0.44089 0.09859 0.37799 0.08452 58021.509909 0.000428 0.12187 0.02894 0.98649 0 2.62315 0.20986 2.24801 0.17986 0.31969 0.07149 0.27443 0.06136 58021.510852 0.000515 0.18669 0.03447 0.98876 0 2.48740 0.18479 2.13540 0.15864 0.46438 0.07850 0.39839 0.06734 58021.511726 0.000359 0.14196 0.03401 0.99194 0 2.66069 0.22857 2.29453 0.19711 0.37772 0.08446 0.32575 0.07284 58021.512406 0.000315 0.17034 0.04187 0.98165 0 2.52108 0.23812 2.16937 0.20490 0.42945 0.09746 0.36960 0.08387 58021.513164 0.000443 0.12619 0.03000 0.98039 0 2.45710 0.19851 2.11710 0.17104 0.31006 0.06933 0.26711 0.05973 58021.513905 0.000298 0.15908 0.03837 0.98058 0 2.89328 0.26140 2.49300 0.22523 0.46026 0.10292 0.39670 0.08870 58021.515068 0.000865 0.14353 0.02104 0.98328 0 3.00959 0.15626 2.56937 0.13340 0.43196 0.05920 0.36947 0.05063
