/* ** ** 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 56221.014614 0.000856 0.11913 0.02823 0.97635 0 1.41338 0.11084 1.16413 0.09128 0.16838 0.03765 0.13864 0.03100 56221.016254 0.000778 0.13311 0.03171 0.97398 0 1.38593 0.11392 1.14883 0.09443 0.18449 0.04125 0.15293 0.03420 56221.018245 0.001212 0.11486 0.02296 0.96709 0 1.45524 0.09483 1.20514 0.07853 0.16714 0.03159 0.13843 0.02616 56221.079119 0.000990 0.10553 0.02483 0.97076 0 1.36132 0.09972 1.14006 0.08351 0.14366 0.03212 0.12068 0.02699 56221.080887 0.000778 0.10644 0.02542 0.98141 0 1.68914 0.12561 1.40920 0.10479 0.17979 0.04081 0.14981 0.03399 56221.082843 0.001178 0.08376 0.01909 0.97543 0 1.55008 0.09755 1.29051 0.08121 0.12984 0.02844 0.10841 0.02374
