/* ** ** Swift/XRT hardness ratio for Mrk 421. ** 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 58511.093579 0.000339 0.16331 0.01255 1.00000 0 22.60015 0.65632 20.87253 0.60614 3.69089 0.26269 3.40910 0.24264 58511.094262 0.000344 0.15644 0.01211 0.99160 0 23.53057 0.66535 21.63614 0.61174 3.68109 0.26525 3.38533 0.24381 58511.094939 0.000333 0.18076 0.01400 0.97391 0 21.56201 0.65310 19.79104 0.59950 3.89760 0.27781 3.58098 0.25524 58511.095622 0.000350 0.15800 0.01231 1.00000 0 22.40744 0.64571 20.68629 0.59611 3.54030 0.25630 3.26829 0.23661 58511.096360 0.000388 0.14384 0.01109 0.99254 0 22.38195 0.61068 20.66160 0.56375 3.21936 0.23215 2.97189 0.21431 58511.097103 0.000356 0.16218 0.01285 0.98374 0 21.64114 0.63207 19.97939 0.58354 3.50974 0.25844 3.24016 0.23859 58511.097757 0.000298 0.17995 0.01411 1.00000 0 23.10261 0.71097 21.32588 0.65629 4.15722 0.29978 3.83749 0.27673 58511.098406 0.000350 0.16055 0.01230 1.00000 0 22.35412 0.64497 20.63620 0.59541 3.58889 0.25479 3.31296 0.23520 58511.099094 0.000339 0.16421 0.01308 0.99145 0 22.06750 0.64992 20.37199 0.59998 3.62371 0.26828 3.34529 0.24767 58511.099745 0.000312 0.16873 0.01309 1.00000 0 23.60394 0.70098 21.78972 0.64710 3.98264 0.28532 3.67651 0.26339 58511.100344 0.000286 0.19286 0.01507 0.98990 0 22.99823 0.72295 21.23143 0.66741 4.43538 0.31738 4.09460 0.29299 58511.100966 0.000336 0.16805 0.01333 1.00000 0 21.66361 0.64412 19.99860 0.59461 3.64062 0.26776 3.36082 0.24718 58511.101626 0.000318 0.17188 0.01348 0.98182 0 22.95846 0.68181 21.19546 0.62946 3.94616 0.28644 3.64314 0.26444 58511.102361 0.000417 0.17807 0.01171 0.99306 0 23.65389 0.60668 21.74123 0.55763 4.21207 0.25502 3.86939 0.23426
