/* ** ** 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 59810.753734 0.000321 0.11942 0.02460 0.97913 0 4.77311 0.32176 4.10504 0.27672 0.57002 0.11093 0.49280 0.09590 59810.755104 0.001031 0.10448 0.02456 0.98592 1 4.30810 0.31269 1.09135 0.07921 0.45010 0.10065 0.11429 0.02556 59810.756905 0.000770 0.15364 0.03697 1.00000 1 3.89396 0.34619 0.98340 0.08742 0.59826 0.13379 0.15094 0.03375 59810.758866 0.001191 0.08617 0.02026 1.00000 1 4.42293 0.29607 1.12349 0.07520 0.38112 0.08590 0.09685 0.02183 59810.760870 0.000813 0.13342 0.03174 0.94643 1 4.46836 0.36265 1.13323 0.09197 0.59615 0.13331 0.15094 0.03375 59810.762366 0.000683 0.16327 0.03968 0.93617 1 4.32186 0.39279 1.10514 0.10044 0.70565 0.15904 0.18050 0.04068 59810.763819 0.000770 0.14376 0.03467 0.98113 1 4.16516 0.35757 1.06133 0.09111 0.59878 0.13494 0.15273 0.03442 59810.765286 0.000697 0.12977 0.03083 0.93747 1 5.42506 0.43492 1.36880 0.10973 0.70403 0.15745 0.17778 0.03975 59810.767697 0.001714 0.11528 0.01975 0.95676 1 4.59017 0.25228 1.16800 0.06419 0.52917 0.08584 0.13464 0.02184
