/* ** ** 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 59695.275989 0.001177 0.24315 0.06177 0.60494 1 1.36462 0.13861 0.64155 0.06516 0.33180 0.07726 0.15700 0.03655 59695.278690 0.001525 0.18740 0.04581 0.59048 1 1.43414 0.12312 0.67784 0.05819 0.26875 0.06152 0.12615 0.02887 59695.281537 0.001322 0.19665 0.04957 0.60440 1 1.52725 0.14462 0.71329 0.06755 0.30034 0.07016 0.13941 0.03257 59695.285169 0.002280 0.17206 0.03624 0.59236 1 1.41266 0.10245 0.66057 0.04790 0.24306 0.04806 0.11310 0.02237 59695.409056 0.001162 0.24375 0.05975 0.65000 1 1.39447 0.13850 0.65129 0.06461 0.33990 0.07617 0.15757 0.03528 59695.411714 0.001467 0.21520 0.05185 0.60524 1 1.41628 0.13915 0.66709 0.06553 0.30478 0.06705 0.14291 0.03143
