/* ** ** 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 54510.447321 0.000767 0.17539 0.02989 0.75094 0 3.07295 0.21687 2.64013 0.18637 0.53897 0.08361 0.46374 0.07192 54510.448707 0.000619 0.26160 0.04652 0.72430 0 2.66837 0.24128 2.29931 0.20796 0.69806 0.10688 0.60216 0.09221 54510.450050 0.000723 0.20262 0.03453 0.78000 0 2.75141 0.21634 2.38796 0.18776 0.55750 0.08430 0.48403 0.07319 54510.451479 0.000700 0.23180 0.04180 0.69008 0 2.66370 0.21553 2.30429 0.18642 0.61745 0.09952 0.53372 0.08604 54510.452950 0.000712 0.31211 0.08138 0.59184 1 3.25542 0.37004 0.84311 0.09586 1.01606 0.23841 0.26333 0.06180 54510.454620 0.000930 0.21527 0.05573 0.57812 1 3.61773 0.33045 0.93168 0.08509 0.77878 0.18865 0.20015 0.04849 54510.456886 0.001336 0.29878 0.05859 0.65217 1 3.03295 0.25913 0.78379 0.06697 0.90617 0.15996 0.23352 0.04123
