/* ** ** 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 57683.152137 0.000859 0.09108 0.02158 0.95960 0 1.79535 0.12206 1.52540 0.10370 0.16352 0.03712 0.13870 0.03149 57683.153645 0.000642 0.11570 0.02773 0.97297 0 1.86076 0.14298 1.58229 0.12158 0.21530 0.04887 0.18301 0.04155 57683.154828 0.000541 0.12211 0.02900 1.00000 0 2.08848 0.16697 1.75116 0.14000 0.25502 0.05703 0.21426 0.04791 57683.156168 0.000799 0.09251 0.02115 0.97826 0 1.99520 0.13578 1.68342 0.11455 0.18458 0.04028 0.15581 0.03400 57683.157638 0.000671 0.11701 0.02813 0.97414 0 1.76878 0.14001 1.49566 0.11838 0.20697 0.04698 0.17491 0.03971 57683.158668 0.000359 0.19976 0.05279 0.97581 0 1.82948 0.19545 1.55110 0.16570 0.36546 0.08834 0.30895 0.07470 57683.159585 0.000558 0.13703 0.03276 0.98446 0 1.82674 0.15441 1.54365 0.13046 0.25032 0.05598 0.21088 0.04715 57683.161318 0.001175 0.11386 0.02038 0.98030 0 1.86758 0.10737 1.57068 0.09029 0.21265 0.03605 0.17851 0.03026
