/* ** ** Swift/XRT hardness ratio for M87. ** 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 55296.838764 0.000382 0.17527 0.04906 0.76515 0 2.51797 0.31578 2.04641 0.25656 0.44132 0.11044 0.35833 0.08962 55296.839938 0.000787 0.21996 0.04012 0.72794 0 2.46887 0.20710 2.03343 0.17058 0.54305 0.08797 0.44717 0.07243 55296.841602 0.000877 0.23340 0.04151 0.63764 0 2.41406 0.19036 1.99224 0.15709 0.56344 0.08981 0.46496 0.07413 55296.843298 0.000819 0.18706 0.03252 0.75265 0 2.75931 0.20137 2.27639 0.16613 0.51615 0.08144 0.42579 0.06718 55296.844739 0.000616 0.24612 0.04336 0.81221 0 2.67155 0.23699 2.20081 0.19523 0.65753 0.10009 0.54166 0.08245 55296.846055 0.000700 0.25081 0.04606 0.76033 0 2.39366 0.22824 1.97406 0.18823 0.60035 0.09424 0.49524 0.07773 55296.847496 0.000729 0.24564 0.04310 0.71429 0 2.56950 0.21458 2.11599 0.17671 0.63118 0.09739 0.51976 0.08020 55296.849010 0.000784 0.22558 0.03881 0.73432 0 2.54261 0.20759 2.09616 0.17115 0.57355 0.08686 0.47305 0.07164 55296.850546 0.000741 0.23218 0.04170 0.76953 0 2.42888 0.21555 2.00234 0.17770 0.56394 0.08806 0.46474 0.07257 55296.852036 0.000744 0.21648 0.03846 0.77432 0 2.57982 0.21863 2.12491 0.18008 0.55849 0.08721 0.46007 0.07184 55296.853891 0.001111 0.18988 0.02890 0.73084 0 2.62525 0.17672 2.16455 0.14570 0.49847 0.06805 0.41089 0.05609 55296.892847 0.000220 0.20574 0.06744 0.73676 0 2.88579 0.43668 2.24558 0.33953 0.59372 0.17265 0.46416 0.13512 55296.909504 0.000773 0.18375 0.03186 0.79775 0 2.73636 0.20421 2.34280 0.17483 0.50280 0.07869 0.42988 0.06727 55296.911012 0.000735 0.19352 0.03499 0.73622 0 2.85106 0.21633 2.41877 0.18357 0.55172 0.09054 0.46953 0.07700 55296.912409 0.000663 0.22021 0.03764 0.74672 0 2.90264 0.22456 2.49152 0.19277 0.63918 0.09743 0.54804 0.08355 55296.913902 0.000830 0.17781 0.02787 0.79791 0 3.13466 0.20959 2.69063 0.17990 0.55739 0.07901 0.47858 0.06785
