/* ** ** 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 54511.132959 0.000428 0.33140 0.05995 0.79730 0 2.85910 0.28557 2.41987 0.24170 0.94751 0.14292 0.80195 0.12096 54511.133986 0.000593 0.25319 0.04363 0.81951 0 2.65923 0.23080 2.25071 0.19534 0.67330 0.10023 0.56986 0.08483 54511.135167 0.000582 0.23109 0.03982 0.78607 0 3.07321 0.24891 2.60109 0.21067 0.71019 0.10802 0.60109 0.09143 54511.136345 0.000590 0.24273 0.04196 0.76961 0 2.91673 0.24105 2.46865 0.20402 0.70797 0.10750 0.59921 0.09098 54511.137574 0.000639 0.20696 0.03657 0.81781 0 2.91246 0.23479 2.46504 0.19872 0.60276 0.09478 0.51016 0.08022 54511.244839 0.000521 0.16463 0.03784 0.75556 0 2.56713 0.24356 2.24032 0.21256 0.42264 0.08848 0.36883 0.07722 54511.246207 0.000842 0.26027 0.03791 0.77143 0 2.60582 0.18603 2.27408 0.16235 0.67821 0.08610 0.59187 0.07514 54511.248005 0.000915 0.18420 0.04894 0.73016 1 3.38218 0.33890 0.86208 0.08639 0.62299 0.15331 0.15869 0.03905 54511.249836 0.000857 0.22397 0.05710 0.64987 1 3.70012 0.38629 0.94094 0.09827 0.82871 0.19273 0.21125 0.04912
