/* ** ** 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 56314.506569 0.000333 0.11202 0.01566 1.00000 0 10.10024 0.45141 8.86147 0.39603 1.13142 0.14987 0.99296 0.13152 56314.507249 0.000347 0.09619 0.01443 0.97500 0 9.89492 0.43699 8.80612 0.38891 0.95175 0.13643 0.84703 0.12142 56314.507920 0.000324 0.09336 0.01417 0.98214 0 10.72552 0.47240 9.54682 0.42049 1.00128 0.14549 0.89125 0.12950 56314.509263 0.001019 0.12155 0.00917 0.99148 0 10.60080 0.26362 9.42066 0.23427 1.28855 0.09181 1.14463 0.08155 56314.510591 0.000310 0.10894 0.01622 0.97196 0 9.93228 0.46160 8.84136 0.41090 1.08198 0.15301 0.96314 0.13621 56314.511222 0.000321 0.10129 0.01504 0.98198 0 10.18912 0.46060 9.07246 0.41012 1.03209 0.14596 0.91896 0.12996 56314.511864 0.000321 0.11147 0.01684 0.99099 0 9.07725 0.43324 8.08276 0.38578 1.01180 0.14503 0.90093 0.12914 56314.513239 0.001053 0.12184 0.00933 0.98077 0 10.15497 0.25306 9.04041 0.22528 1.23725 0.08958 1.10144 0.07975 56314.515119 0.000828 0.10775 0.00975 0.97552 0 10.28489 0.28681 9.15630 0.25533 1.10822 0.09538 0.98663 0.08491 56314.516259 0.000312 0.10471 0.01564 0.97222 0 10.42678 0.47136 9.28179 0.41960 1.09174 0.15539 0.97185 0.13833 56314.517998 0.001427 0.12175 0.00824 0.96957 0 9.62885 0.21177 8.56149 0.18829 1.17230 0.07504 1.04279 0.06675
