/* ** ** 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 54714.911503 0.000295 0.17137 0.02654 0.99020 0 6.37875 0.37617 5.73504 0.33819 1.09313 0.15655 0.98183 0.14060 54714.912111 0.000312 0.15942 0.02386 0.99074 0 6.86756 0.38119 6.15979 0.34191 1.09486 0.15218 0.98295 0.13662 54714.913537 0.001114 0.16997 0.01315 0.97143 0 7.06934 0.20608 6.25323 0.18227 1.20156 0.08609 1.06327 0.07618 54714.914967 0.000315 0.14866 0.02261 0.98165 0 7.18018 0.39440 6.35639 0.34914 1.06741 0.15135 0.94550 0.13403 54714.915580 0.000298 0.17859 0.02775 0.98058 0 6.23482 0.37643 5.48954 0.33142 1.11348 0.15945 0.98183 0.14060 54714.916286 0.000408 0.11505 0.01825 0.97872 0 6.73338 0.33371 5.99560 0.29712 0.77466 0.11675 0.68956 0.10392 54714.917102 0.000408 0.16308 0.02160 1.00000 0 6.72796 0.33334 5.98839 0.29668 1.09721 0.13476 0.97325 0.11951 54714.917936 0.000425 0.11320 0.01688 0.96599 0 6.99224 0.33080 6.22269 0.29437 0.79149 0.11194 0.70540 0.09976 54714.919217 0.000856 0.15643 0.01447 0.96959 0 6.99502 0.23361 6.22197 0.20778 1.09424 0.09439 0.97375 0.08398 54714.920386 0.000312 0.14864 0.02307 0.96296 0 7.18240 0.39779 6.34076 0.35117 1.06762 0.15482 0.94388 0.13689 54714.921199 0.000501 0.12452 0.01641 0.98408 0 6.95368 0.30533 6.18963 0.27180 0.86584 0.10759 0.77076 0.09578 54714.977825 0.000330 0.13696 0.02120 1.00000 0 7.19039 0.38573 6.28232 0.33703 0.98480 0.14296 0.86054 0.12492 54714.978765 0.000611 0.17099 0.01858 0.99052 0 6.62037 0.27248 5.72203 0.23546 1.13205 0.11387 0.97711 0.09825 54714.980079 0.000703 0.14228 0.01553 0.97942 0 6.51455 0.25257 5.68424 0.22038 0.92691 0.09460 0.80807 0.08247
