/* ** ** 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 54534.758245 0.000764 0.19256 0.03690 0.74021 0 2.45670 0.21355 2.07241 0.18018 0.47307 0.08078 0.39834 0.06806 54534.760124 0.001104 0.28205 0.07136 0.60526 1 2.55698 0.27284 0.60225 0.06426 0.72121 0.16544 0.16964 0.03892 54534.762550 0.001322 0.32275 0.07425 0.49253 1 2.82485 0.26603 0.67213 0.06330 0.91172 0.19138 0.21724 0.04559 54534.826161 0.000891 0.18327 0.03402 0.78247 0 5.80805 0.49879 2.04155 0.17138 1.06446 0.17515 0.36051 0.05830 54534.828429 0.001377 0.22999 0.03286 0.71887 0 5.72319 0.40668 1.88710 0.13403 1.31626 0.16317 0.43339 0.05367 54534.892453 0.000446 0.15787 0.04154 0.74675 0 2.67305 0.30103 2.06601 0.23234 0.42200 0.10037 0.33022 0.07843 54534.893671 0.000773 0.20781 0.03754 0.74157 0 2.76297 0.23151 2.18470 0.18304 0.57416 0.09188 0.45307 0.07251 54534.895190 0.065344 0.27604 0.05405 0.01399 1 2.12397 0.16842 0.76730 0.06058 0.58630 0.10496 0.21118 0.03766 54534.895210 0.000767 0.21322 0.03650 0.74717 0 2.84108 0.23788 2.25917 0.18917 0.60576 0.09045 0.48212 0.07198 54534.896964 0.000987 0.28270 0.04217 0.69665 0 2.61280 0.20250 2.07929 0.16115 0.73863 0.09415 0.58770 0.07491 54534.958708 0.000098 0.10088 0.06794 0.81838 0 2.78057 0.63423 2.29796 0.52411 0.28049 0.17775 0.23271 0.14749 54534.961522 0.000901 0.22534 0.05913 0.66129 1 2.12456 0.22463 0.81256 0.08590 0.47875 0.11497 0.18202 0.04373 54534.963439 0.001017 0.26156 0.06363 0.68571 1 1.79286 0.18741 0.69862 0.07303 0.46895 0.10301 0.18224 0.04003
