/* ** ** 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 55356.162130 0.000489 0.08883 0.02104 0.98817 0 3.07781 0.20807 2.66890 0.18042 0.27340 0.06206 0.23675 0.05374 55356.163018 0.000399 0.13771 0.03288 0.99275 0 2.45298 0.20526 2.12251 0.17759 0.33781 0.07554 0.29246 0.06540 55356.163964 0.000547 0.08166 0.01900 0.98942 0 3.03881 0.19591 2.62395 0.16915 0.24815 0.05549 0.21426 0.04791 55356.164893 0.000376 0.11050 0.02642 0.99231 0 3.25757 0.24431 2.77161 0.20785 0.35997 0.08173 0.30649 0.06957 55356.165565 0.000295 0.13683 0.03368 0.99020 0 3.27066 0.28187 2.81328 0.24242 0.44751 0.10318 0.38622 0.08901 55356.166314 0.000454 0.10413 0.02483 0.96178 0 2.95422 0.21556 2.52274 0.18407 0.30762 0.06985 0.26184 0.05944 55356.167234 0.000466 0.10165 0.02388 0.98137 0 2.92085 0.21022 2.48968 0.17918 0.29691 0.06640 0.25359 0.05670 55356.168010 0.000310 0.14233 0.03326 0.99065 0 3.26590 0.27276 2.80109 0.23388 0.46485 0.10145 0.39689 0.08661 55356.168831 0.000512 0.14946 0.02749 0.96610 0 3.08193 0.20464 2.66898 0.17721 0.46061 0.07900 0.39832 0.06831 55356.169644 0.000301 0.16667 0.04027 0.98077 0 2.77683 0.25409 2.36149 0.21608 0.46281 0.10349 0.39281 0.08784 55356.170377 0.000431 0.11059 0.02610 0.98658 0 2.90117 0.21928 2.45796 0.18579 0.32085 0.07175 0.27256 0.06095 55356.171164 0.000356 0.12179 0.02753 0.95935 0 3.60530 0.27036 3.05848 0.22935 0.43909 0.09362 0.37350 0.07963
