/* ** ** Swift/XRT hardness ratio for 3C 273. ** 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 58524.441597 0.000367 0.33309 0.08208 0.95276 0 2.29729 0.28314 1.20800 0.14554 0.76521 0.16327 0.38862 0.08134 58524.442465 0.000501 0.19055 0.04775 0.98266 0 2.23407 0.23363 1.19698 0.12464 0.42571 0.09694 0.23258 0.05279 58524.443307 0.000341 0.28088 0.07290 0.97458 0 2.17975 0.27373 1.22479 0.15373 0.61226 0.13907 0.34381 0.07804 58524.444126 0.000477 0.26480 0.06712 0.96970 0 1.70771 0.20385 0.94819 0.11319 0.45221 0.10112 0.25042 0.05599 58524.445272 0.000668 0.40444 0.06904 0.96970 0 1.93481 0.17747 1.08839 0.09983 0.78252 0.11265 0.44010 0.06337 58524.446247 0.000307 0.30061 0.07703 0.96226 0 2.34088 0.29269 1.31581 0.16441 0.70369 0.15739 0.39281 0.08784 58524.446860 0.000307 0.46488 0.12936 0.95283 0 1.51028 0.24294 0.84235 0.13548 0.70210 0.15942 0.39147 0.08886 58524.447531 0.000365 0.29169 0.07262 0.96825 0 2.07510 0.24850 1.17650 0.14081 0.60528 0.13213 0.34484 0.07525 58524.448576 0.000674 0.32263 0.05545 0.96996 0 2.15836 0.18450 1.23350 0.10544 0.69635 0.10382 0.39889 0.05946 58524.449554 0.000304 0.31817 0.08328 0.97143 0 2.13908 0.27893 1.21575 0.15853 0.68059 0.15446 0.38763 0.08799 58524.450445 0.000587 0.32124 0.05936 0.96552 0 2.17638 0.20059 1.24564 0.11482 0.69915 0.11197 0.39862 0.06383 58524.451357 0.000324 0.29103 0.07492 0.96429 0 2.18701 0.26560 1.25847 0.15282 0.63648 0.14447 0.36610 0.08310 58524.452558 0.000877 0.41837 0.06368 0.98020 0 1.74202 0.14721 1.01221 0.08553 0.72881 0.09226 0.42317 0.05357
