/* ** ** 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 53950.062937 0.000301 0.11136 0.01659 0.97115 0 9.93831 0.46451 8.90082 0.41602 1.10672 0.15652 0.99175 0.14025 53950.063545 0.000307 0.10837 0.01601 0.99057 0 10.17340 0.47018 9.05523 0.41851 1.10251 0.15468 0.98282 0.13790 53950.064835 0.000984 0.12796 0.00971 0.97059 0 10.52760 0.26543 9.39486 0.23686 1.34712 0.09642 1.20229 0.08606 53950.066823 0.001004 0.12504 0.00952 0.98559 0 10.36246 0.26122 9.27834 0.23387 1.29573 0.09308 1.16025 0.08334 53950.068701 0.000874 0.14173 0.01089 0.98675 0 10.55727 0.28350 9.34638 0.25095 1.49632 0.10776 1.32484 0.09541 53950.070634 0.001059 0.12057 0.00910 0.98087 0 10.32051 0.25381 9.18145 0.22580 1.24434 0.08880 1.10790 0.07906 53950.072729 0.001036 0.11626 0.00884 0.98324 0 10.81373 0.26335 9.63806 0.23471 1.25720 0.09056 1.12160 0.08077 53950.074080 0.000315 0.10498 0.01567 0.98165 0 10.34480 0.46726 9.21179 0.41608 1.08605 0.15445 0.96490 0.13722 53950.074699 0.000304 0.09723 0.01440 0.97143 0 11.38004 0.49850 10.09466 0.44219 1.10650 0.15649 0.98203 0.13888 53950.075298 0.000295 0.10462 0.01575 0.99020 0 10.61505 0.49155 9.36403 0.43361 1.11059 0.15903 0.98207 0.14059 53950.075894 0.000301 0.10743 0.01600 0.99038 0 10.12607 0.47267 9.06597 0.42318 1.08780 0.15385 0.97249 0.13753 53950.077208 0.001013 0.12299 0.00925 0.98286 0 10.61299 0.26287 9.45286 0.23412 1.30534 0.09264 1.16487 0.08266 53950.079728 0.001508 0.11685 0.00752 0.98464 0 10.35419 0.21296 9.21325 0.18948 1.20990 0.07374 1.07629 0.06560
