/* ** ** 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 56193.097430 0.000550 0.08238 0.01971 0.95789 0 3.21172 0.20725 2.59800 0.16762 0.26458 0.06095 0.21437 0.04940 56193.098396 0.000417 0.10535 0.02477 0.95139 0 3.41709 0.24841 2.77694 0.20188 0.36000 0.08050 0.29246 0.06540 56193.099247 0.000434 0.09982 0.02447 0.96000 0 3.30760 0.24259 2.67840 0.19641 0.33015 0.07723 0.26728 0.06254 56193.100242 0.000561 0.07608 0.01790 0.96392 0 3.42961 0.21299 2.77923 0.17258 0.26093 0.05922 0.21145 0.04799 56193.101327 0.000524 0.09079 0.02150 0.96133 0 3.08824 0.20893 2.49980 0.16910 0.28038 0.06364 0.22725 0.05158 56193.102661 0.000810 0.10014 0.01731 0.97959 0 3.38908 0.17738 2.73325 0.14305 0.33940 0.05592 0.27371 0.04511
