/* ** ** 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 59264.423952 0.000842 0.29359 0.07776 0.63793 1 1.55132 0.19025 0.69930 0.08577 0.45545 0.10692 0.20637 0.04844 59264.425506 0.000683 0.26142 0.06819 0.70213 1 1.91070 0.21719 0.88410 0.10048 0.49950 0.11726 0.23139 0.05431 59264.427133 0.000944 0.25558 0.06486 0.60000 1 1.69512 0.17199 0.77727 0.07883 0.43324 0.10077 0.19749 0.04594 59264.428934 0.000857 0.30353 0.07857 0.55932 1 1.66077 0.17749 0.75694 0.08091 0.50410 0.11884 0.23038 0.05432 59264.430444 0.000596 0.24847 0.06413 0.80488 1 2.08313 0.24156 0.94925 0.11006 0.51760 0.11934 0.23540 0.05427 59264.432158 0.001118 0.25056 0.05776 0.67532 1 1.65596 0.16002 0.74868 0.07233 0.41492 0.08684 0.18790 0.03932
