/* ** ** 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 54687.000167 0.000020 0.07143 0.05228 0.86974 0 10.17344 1.92260 9.21179 1.74087 0.72668 0.51384 0.65799 0.46527 54687.002716 0.000392 0.20015 0.04879 0.92593 1 6.32454 0.61387 1.59515 0.15481 1.26585 0.28306 0.32000 0.07155 54687.003807 0.000095 0.17981 0.04766 0.96073 0 6.85693 0.71993 6.14690 0.64537 1.23294 0.30010 1.10771 0.26965 54687.004067 0.000959 0.13562 0.03196 0.59117 1 6.30898 0.50538 1.57458 0.12613 0.85563 0.18960 0.21227 0.04703 54687.005606 0.000581 0.11987 0.02838 0.97500 1 6.80913 0.53025 1.71367 0.13344 0.81619 0.18251 0.20513 0.04587 54687.006609 0.000392 0.19577 0.04663 0.96296 1 6.54040 0.62398 1.65222 0.15763 1.28040 0.27941 0.32308 0.07050 54687.007451 0.000450 0.18658 0.04438 0.96774 1 6.01195 0.56881 1.49880 0.14179 1.12169 0.24480 0.28000 0.06110 54687.008323 0.000421 0.17169 0.04148 0.93103 1 6.89506 0.63006 1.72811 0.15789 1.18380 0.26474 0.29629 0.06625 54687.009165 0.000421 0.17241 0.04208 0.96552 1 6.56139 0.61430 1.64450 0.15395 1.13123 0.25496 0.28361 0.06392 54687.010124 0.000537 0.15780 0.03716 0.97297 1 5.91788 0.52343 1.48029 0.13091 0.93386 0.20380 0.23333 0.05092 54687.011562 0.000901 0.11796 0.02343 0.98265 1 6.35986 0.41235 1.60055 0.10377 0.75020 0.14083 0.18846 0.03538
