/* ** ** 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 56921.577319 0.000637 0.12521 0.03015 0.97273 0 3.52951 0.28373 1.47582 0.11864 0.44192 0.10029 0.18478 0.04194 56921.578639 0.000683 0.09096 0.02155 0.96186 0 4.58001 0.31141 1.91508 0.13021 0.41661 0.09455 0.17420 0.03954 56921.580120 0.000799 0.08095 0.01966 0.98551 0 4.18144 0.27327 1.74842 0.11426 0.33849 0.07918 0.14154 0.03311 56921.581451 0.000532 0.13784 0.03290 0.97283 0 3.88374 0.32441 1.62394 0.13565 0.53532 0.11970 0.22384 0.05005 56921.582664 0.000680 0.15865 0.03291 0.97334 0 3.56475 0.27614 1.49056 0.11546 0.56554 0.10884 0.23647 0.04551 56921.707808 0.000405 0.11831 0.02843 0.97143 0 2.81469 0.22176 2.45729 0.19360 0.33301 0.07559 0.29073 0.06599 56921.708705 0.000492 0.09258 0.02113 0.98235 0 3.11692 0.20877 2.72114 0.18226 0.28856 0.06297 0.25192 0.05497 56921.709555 0.000359 0.12828 0.03099 0.99194 0 2.87031 0.23712 2.50585 0.20701 0.36821 0.08358 0.32145 0.07297 56921.710247 0.000333 0.12790 0.03083 0.98261 0 3.13362 0.25448 2.73573 0.22217 0.40079 0.09097 0.34990 0.07942 56921.710988 0.000408 0.08683 0.02055 1.00000 0 3.69910 0.24714 3.22941 0.21576 0.32120 0.07291 0.28042 0.06365 56921.711966 0.000570 0.07487 0.01696 1.00000 0 3.26714 0.19880 2.85229 0.17356 0.24461 0.05338 0.21355 0.04660 56921.712889 0.000353 0.12493 0.02968 0.98361 0 3.06127 0.24553 2.67256 0.21436 0.38245 0.08552 0.33389 0.07466 56921.713595 0.000353 0.11123 0.02701 0.99180 0 3.32021 0.25414 2.89862 0.22187 0.36929 0.08511 0.32240 0.07430 56921.714272 0.000324 0.11608 0.02743 0.96429 0 3.66082 0.27973 3.19599 0.24421 0.42495 0.09502 0.37099 0.08296 56921.714891 0.000295 0.12437 0.02955 0.99020 0 3.65363 0.29376 3.18971 0.25646 0.45440 0.10161 0.39670 0.08870 56921.715510 0.000324 0.13418 0.03246 0.98214 0 3.06850 0.25710 2.67888 0.22445 0.41172 0.09345 0.35944 0.08159 56921.716587 0.000752 0.11274 0.01944 0.97692 0 3.02403 0.16545 2.64005 0.14444 0.34092 0.05574 0.29763 0.04866
