/* ** ** 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 57962.193264 0.000891 0.12899 0.03121 0.98377 0 1.77060 0.14442 1.07032 0.08668 0.22840 0.05203 0.13087 0.02960 57962.194907 0.000752 0.11783 0.02855 0.98462 0 1.98537 0.15803 1.29935 0.10343 0.23393 0.05353 0.15328 0.03507 57962.196432 0.000773 0.14215 0.03442 0.97753 0 1.63471 0.14137 1.06871 0.09242 0.23237 0.05256 0.15193 0.03436 57962.197882 0.000677 0.16355 0.03957 0.97863 0 1.64207 0.15156 1.06738 0.09852 0.26857 0.06005 0.17496 0.03912 57962.199595 0.001036 0.09574 0.02246 0.96927 0 1.86083 0.13173 1.20749 0.08547 0.17815 0.03984 0.11547 0.02582 57962.201629 0.000998 0.10419 0.02477 0.96232 0 1.76440 0.12899 1.14493 0.08370 0.18382 0.04158 0.11944 0.02701 57962.203701 0.001073 0.10433 0.02482 0.96226 0 1.65446 0.12227 1.06951 0.07903 0.17262 0.03904 0.11107 0.02512 57962.205831 0.001056 0.09904 0.02381 0.97808 0 1.71708 0.12666 1.10919 0.08182 0.17005 0.03891 0.10991 0.02515 57962.207954 0.001068 0.15003 0.02769 0.98374 0 1.94013 0.13245 1.24862 0.08524 0.29109 0.04992 0.18764 0.03218
