/* ** ** 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 55729.458852 0.000556 0.11009 0.02678 0.98438 0 2.18346 0.16681 1.86928 0.14281 0.24037 0.05551 0.20607 0.04759 55729.459905 0.000498 0.12236 0.02903 0.98256 0 2.29018 0.18142 1.93759 0.15350 0.28023 0.06267 0.23708 0.05301 55729.460938 0.000535 0.11672 0.02759 0.96757 0 2.26846 0.17362 1.91756 0.14677 0.26478 0.05921 0.22384 0.05005 55729.461965 0.000492 0.12924 0.03071 0.96471 0 2.23661 0.17976 1.88994 0.15188 0.28906 0.06464 0.24431 0.05463 55729.462877 0.000420 0.12811 0.03142 0.98621 0 2.53246 0.21052 2.12677 0.17678 0.32443 0.07487 0.27236 0.06290 55729.463861 0.000564 0.10726 0.02525 0.97436 0 2.32788 0.17128 1.96376 0.14450 0.24969 0.05583 0.21088 0.04715 55729.464868 0.000443 0.12614 0.03043 0.97386 0 2.52242 0.20461 2.10917 0.17110 0.31817 0.07229 0.26515 0.06025 55729.465860 0.000550 0.10290 0.02417 0.97368 0 2.49423 0.17911 2.09675 0.15056 0.25664 0.05739 0.21658 0.04843 55729.466948 0.000538 0.12345 0.03016 0.97312 0 2.07145 0.16608 1.73966 0.13947 0.25573 0.05902 0.21518 0.04969 55729.468062 0.000576 0.10465 0.02461 0.98492 0 2.32266 0.16907 1.95460 0.14229 0.24307 0.05436 0.20442 0.04571 55729.469714 0.001076 0.09829 0.01839 0.97043 0 2.14442 0.11965 1.79125 0.09993 0.21078 0.03763 0.17603 0.03143
