/* ** ** 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 58004.184261 0.000541 0.12166 0.02973 0.97861 0 2.07550 0.16783 1.74944 0.14144 0.25252 0.05823 0.21306 0.04913 58004.185604 0.000802 0.07841 0.01822 0.97112 0 2.24820 0.14204 1.89556 0.11975 0.17627 0.03942 0.14895 0.03331 58004.187053 0.000648 0.09356 0.02223 0.96429 0 2.31229 0.16165 1.95600 0.13674 0.21634 0.04912 0.18300 0.04155 58004.188243 0.000541 0.10377 0.02442 0.97861 0 2.49143 0.18308 2.10916 0.15499 0.25853 0.05781 0.21894 0.04896 58004.189886 0.001102 0.10789 0.01885 0.97993 0 2.15916 0.11919 1.82733 0.10088 0.23296 0.03862 0.19709 0.03267 58004.383497 0.000460 0.13916 0.03367 0.94969 0 2.27132 0.18939 1.89088 0.15768 0.31607 0.07179 0.26169 0.05944 58004.384441 0.000483 0.13514 0.03223 0.95210 0 2.27327 0.18825 1.85705 0.15379 0.30721 0.06870 0.25199 0.05635 58004.385679 0.000755 0.08387 0.01955 0.96552 0 2.32277 0.15321 1.89686 0.12512 0.19481 0.04356 0.15899 0.03555 58004.387042 0.000608 0.10057 0.02367 0.97143 0 2.36787 0.17376 1.94756 0.14292 0.23813 0.05325 0.19641 0.04392 58004.388167 0.000518 0.10713 0.02639 0.96089 0 2.52364 0.19091 2.08820 0.15794 0.27035 0.06339 0.22331 0.05238 58004.389470 0.000784 0.12858 0.02460 0.97417 0 2.19947 0.14494 1.82584 0.12031 0.28280 0.05080 0.23524 0.04225
