/* ** ** 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 54512.137887 0.000637 0.22629 0.03963 0.76818 0 2.82745 0.22939 2.41884 0.19623 0.63983 0.09929 0.54562 0.08470 54512.139288 0.000764 0.18593 0.03278 0.79545 0 2.75551 0.21357 2.31632 0.17955 0.51233 0.08113 0.43152 0.06830 54512.141215 0.001163 0.21493 0.02920 0.74544 0 2.85331 0.17267 2.41320 0.14612 0.61327 0.07461 0.51966 0.06323 54512.207218 0.000567 0.26504 0.04654 0.78571 0 2.66181 0.23344 2.30030 0.20175 0.70548 0.10732 0.60983 0.09273 54512.208764 0.000978 0.27355 0.03808 0.71717 0 2.61802 0.17974 2.26626 0.15559 0.71617 0.08674 0.61998 0.07509 54512.249150 0.000399 0.19016 0.05182 0.80435 0 2.35574 0.29614 1.88294 0.23660 0.44797 0.10831 0.35502 0.08580 54512.250212 0.000663 0.24119 0.04492 0.73799 0 2.76177 0.25919 2.19396 0.20585 0.66610 0.10716 0.52828 0.08499 54512.251731 0.000851 0.18713 0.03111 0.78912 0 2.90522 0.22560 2.30440 0.17892 0.54367 0.07993 0.43084 0.06334 54512.253027 0.000421 0.29730 0.09721 0.66178 1 4.44356 0.63722 0.93131 0.13357 1.32108 0.38819 0.27691 0.08137
