/* ** ** 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 55843.237116 0.000428 0.16571 0.04057 0.96622 0 2.04329 0.18799 1.66566 0.15324 0.33859 0.07682 0.27662 0.06275 55843.237845 0.000301 0.19441 0.04830 0.98077 0 2.46338 0.24974 1.98789 0.20154 0.47891 0.10862 0.38782 0.08798 55843.238571 0.000425 0.13658 0.03261 0.97959 0 2.51978 0.21063 2.04182 0.17066 0.34416 0.07696 0.27824 0.06222 55843.239393 0.000396 0.13209 0.03146 0.96350 0 2.82292 0.23114 2.28757 0.18731 0.37289 0.08339 0.30354 0.06787 55843.240319 0.000530 0.10487 0.02467 0.97268 0 2.61642 0.19139 2.14720 0.15707 0.27438 0.06135 0.22509 0.05033 55843.241395 0.000547 0.10207 0.02467 0.99471 0 2.48424 0.18335 2.03042 0.14986 0.25356 0.05836 0.20770 0.04781 55843.242356 0.000414 0.14869 0.03490 1.00000 0 2.42320 0.20923 1.97036 0.17012 0.36031 0.07863 0.29420 0.06420 55843.243123 0.000353 0.15464 0.03714 0.95902 0 2.71136 0.23749 2.20957 0.19354 0.41928 0.09376 0.34245 0.07657 55843.243841 0.000365 0.13624 0.03248 0.96032 0 2.98649 0.24690 2.43424 0.20123 0.40689 0.09099 0.33113 0.07404 55843.244871 0.000666 0.09927 0.02081 0.96370 0 2.80354 0.17554 2.27572 0.14247 0.27832 0.05567 0.22596 0.04519
