/* ** ** 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 56519.049539 0.000457 0.10594 0.02532 0.97468 0 2.96030 0.22099 2.42310 0.18087 0.31360 0.07121 0.25677 0.05828 56519.050311 0.000315 0.15334 0.03601 0.97248 0 3.14972 0.27338 2.58803 0.22463 0.48299 0.10540 0.39689 0.08661 56519.051023 0.000396 0.11980 0.02842 0.99270 0 2.98881 0.23660 2.45706 0.19451 0.35807 0.08007 0.29461 0.06588 56519.051963 0.000544 0.09366 0.02192 0.96809 0 2.86873 0.19849 2.35023 0.16261 0.26868 0.06008 0.22015 0.04923 56519.052823 0.000315 0.15536 0.03737 0.97248 0 2.95362 0.26203 2.43220 0.21577 0.45888 0.10261 0.37799 0.08452 56519.053546 0.000408 0.11296 0.02666 0.97872 0 3.12520 0.23596 2.56998 0.19405 0.35302 0.07894 0.29034 0.06492 56519.054339 0.000385 0.12330 0.02968 0.97744 0 3.01983 0.24215 2.47113 0.19812 0.37236 0.08450 0.30417 0.06903 56519.055106 0.000382 0.13277 0.03157 0.96212 0 2.90547 0.23518 2.37247 0.19203 0.38575 0.08626 0.31549 0.07054 56519.056101 0.000613 0.07581 0.01760 0.97642 0 3.11692 0.19505 2.54933 0.15953 0.23629 0.05284 0.19356 0.04328 56519.057198 0.000483 0.10852 0.02591 0.96407 0 2.77444 0.20605 2.26029 0.16787 0.30107 0.06833 0.24561 0.05574 56519.058066 0.000385 0.13406 0.03196 0.98496 0 2.77682 0.22931 2.28000 0.18828 0.37227 0.08324 0.30585 0.06839 56519.059003 0.000553 0.08742 0.02037 0.93194 0 3.12904 0.20515 2.57525 0.16884 0.27354 0.06116 0.22509 0.05033 56519.059984 0.000428 0.14196 0.03167 0.95946 0 2.77821 0.22011 2.28418 0.18097 0.39440 0.08224 0.32448 0.06766
