/* ** ** 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 56847.928033 0.000408 0.11717 0.02773 0.98582 0 2.91076 0.22536 2.46344 0.19071 0.34104 0.07626 0.28825 0.06445 56847.928792 0.000350 0.15889 0.03829 0.97521 0 2.52206 0.22663 2.13287 0.19164 0.40073 0.08961 0.33955 0.07593 56847.929538 0.000396 0.12039 0.02888 0.97080 0 2.88348 0.22478 2.47023 0.19257 0.34714 0.07876 0.29740 0.06747 56847.930548 0.000613 0.08276 0.01927 0.97642 0 2.72810 0.17663 2.33849 0.15141 0.22579 0.05049 0.19356 0.04328 56847.931503 0.000341 0.13695 0.03268 0.97458 0 2.98819 0.24923 2.54186 0.21202 0.40923 0.09151 0.34841 0.07791 56847.932145 0.000301 0.15540 0.03741 0.97115 0 2.98246 0.26584 2.55266 0.22753 0.46346 0.10363 0.39670 0.08870 56847.932767 0.000321 0.14449 0.03465 0.98198 0 2.97774 0.25824 2.53145 0.21951 0.43024 0.09621 0.36758 0.08219 56847.933447 0.000359 0.14423 0.03193 0.97581 0 3.18413 0.25319 2.72599 0.21676 0.45925 0.09488 0.39311 0.08122 56847.934257 0.000451 0.11247 0.02690 0.96154 0 2.74892 0.20739 2.34616 0.17699 0.30916 0.07016 0.26369 0.05983 56847.935065 0.000356 0.11200 0.02681 0.95122 0 3.57595 0.27281 3.01700 0.23015 0.40051 0.09087 0.33806 0.07670 56847.935869 0.000448 0.13800 0.02809 0.94194 0 3.27665 0.22738 2.80178 0.19441 0.45216 0.08654 0.38738 0.07414 56847.936636 0.000318 0.13450 0.03209 0.99091 0 3.18676 0.26492 2.73306 0.22720 0.42862 0.09584 0.36758 0.08219 56847.937322 0.000367 0.11662 0.02754 0.95276 0 3.33984 0.25361 2.84265 0.21586 0.38949 0.08710 0.33113 0.07404 56847.938045 0.000356 0.12439 0.02950 0.96748 0 3.16330 0.25009 2.70796 0.21409 0.39347 0.08798 0.33670 0.07529 56847.938731 0.000330 0.13981 0.03335 0.93860 0 3.17529 0.26397 2.68291 0.22304 0.44393 0.09927 0.37446 0.08373 56847.939373 0.000312 0.13417 0.03294 0.98148 0 3.22500 0.27426 2.75096 0.23393 0.43270 0.09964 0.36831 0.08480 56847.940308 0.000622 0.11737 0.02214 0.96744 0 3.04820 0.18666 2.60224 0.15935 0.35777 0.06382 0.30574 0.05454
