/* ** ** Swift/XRT hardness ratio for PKS 2155-304. ** 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 56214.734020 0.001027 0.09169 0.02177 0.98592 0 1.44564 0.10037 1.23172 0.08552 0.13254 0.03010 0.11295 0.02564 56214.736089 0.001042 0.09584 0.02246 0.96389 0 1.42154 0.09968 1.20317 0.08436 0.13625 0.03047 0.11547 0.02582 56214.738146 0.001016 0.10841 0.02553 0.96581 0 1.28814 0.09502 1.09031 0.08042 0.13964 0.03123 0.11819 0.02643 56214.740241 0.001079 0.09038 0.02143 0.98123 0 1.40965 0.09636 1.19613 0.08176 0.12741 0.02892 0.10801 0.02452 56214.742160 0.000839 0.12106 0.02868 0.96207 0 1.40037 0.10949 1.18855 0.09293 0.16953 0.03791 0.14361 0.03211 56214.744066 0.001068 0.10982 0.02425 0.97290 0 1.44265 0.09860 1.22119 0.08346 0.15844 0.03327 0.13356 0.02806
