/* ** ** 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 55480.417188 0.000755 0.13298 0.03211 0.96935 0 1.36270 0.11210 1.17478 0.09664 0.18121 0.04114 0.15624 0.03548 55480.418921 0.000978 0.08452 0.02001 0.97929 0 1.63740 0.10889 1.41068 0.09380 0.13840 0.03144 0.11942 0.02712 55480.420684 0.000784 0.11719 0.02856 0.98524 0 1.44863 0.11426 1.24254 0.09799 0.16976 0.03914 0.14604 0.03368 55480.422258 0.000790 0.11399 0.02732 0.99267 0 1.48522 0.11386 1.27780 0.09795 0.16930 0.03845 0.14586 0.03312 55480.423965 0.000917 0.09572 0.02278 0.99054 0 1.52519 0.10889 1.31702 0.09403 0.14599 0.03314 0.12589 0.02858 55480.425588 0.000706 0.13016 0.03145 0.98361 0 1.46318 0.12094 1.26500 0.10456 0.19045 0.04324 0.16470 0.03740 55480.426910 0.000616 0.16044 0.03875 0.98122 0 1.38143 0.12612 1.19472 0.10907 0.22163 0.04956 0.19171 0.04287 55480.428158 0.000631 0.13902 0.03369 0.98165 0 1.53701 0.13009 1.32858 0.11245 0.21368 0.04852 0.18472 0.04194 55480.429980 0.001192 0.11654 0.02373 0.98301 0 1.32930 0.08855 1.14745 0.07643 0.15491 0.02981 0.13356 0.02570
