/* ** ** 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 57313.594630 0.000436 0.20557 0.05100 1.00000 1 5.07579 0.52619 1.29054 0.13377 1.04345 0.23516 0.26473 0.05966 57313.595647 0.000581 0.17934 0.04363 0.97500 1 4.48409 0.42954 1.13960 0.10916 0.80416 0.17983 0.20513 0.04587 57313.598101 0.001874 0.10963 0.01879 0.98284 1 4.32861 0.23315 1.10515 0.05952 0.47455 0.07722 0.12121 0.01972 57313.993920 0.000610 0.19816 0.04862 1.00000 1 3.80686 0.38448 0.96152 0.09710 0.75436 0.16870 0.19048 0.04259 57313.995068 0.000537 0.20378 0.05004 0.97297 1 4.35784 0.44220 1.09013 0.11063 0.88805 0.19859 0.22222 0.04969 57313.996753 0.001148 0.14440 0.03032 0.96810 1 3.71621 0.27864 0.93546 0.07014 0.53661 0.10525 0.13598 0.02667
