/* ** ** 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 58025.296264 0.000532 0.14437 0.03474 0.98370 0 4.57046 0.40360 1.53082 0.13490 0.65985 0.14772 0.22136 0.04950 58025.297838 0.001042 0.07086 0.01669 0.98056 0 4.71125 0.29274 1.56673 0.09723 0.33385 0.07586 0.11206 0.02542 58025.299678 0.000799 0.10459 0.02462 0.96739 0 4.23015 0.31033 1.43789 0.10545 0.44245 0.09895 0.15006 0.03356 58025.301223 0.000747 0.10010 0.02388 0.97287 0 4.70691 0.34253 1.57523 0.11457 0.47117 0.10703 0.15759 0.03575 58025.302974 0.001004 0.08623 0.02014 0.95677 0 4.13487 0.27714 1.40006 0.09378 0.35655 0.07978 0.12068 0.02699 58025.304776 0.000799 0.11125 0.02631 0.98551 0 4.03856 0.30896 1.33630 0.10217 0.44928 0.10055 0.14730 0.03294 58025.306307 0.000732 0.11156 0.02635 0.95652 0 4.40009 0.33361 1.47709 0.11196 0.49088 0.10980 0.16556 0.03702 58025.307702 0.000663 0.13753 0.03287 0.96070 0 3.88016 0.32660 1.32586 0.11158 0.53365 0.11936 0.18212 0.04072 58025.309082 0.000718 0.12264 0.02919 0.95968 0 4.14903 0.32989 1.40179 0.11149 0.50883 0.11417 0.17247 0.03869 58025.310378 0.000579 0.12419 0.02957 0.97000 0 5.02983 0.41068 1.66331 0.13577 0.62463 0.13973 0.20653 0.04618 58025.312077 0.001120 0.11945 0.02213 0.96382 0 4.50629 0.27941 1.50159 0.09305 0.53829 0.09397 0.17987 0.03138
