/* ** ** 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 56868.460719 0.000417 0.10829 0.02595 0.98611 0 3.54088 0.26639 2.52807 0.19005 0.38343 0.08726 0.27852 0.06320 56868.461564 0.000428 0.10304 0.02456 0.97297 0 3.51816 0.25713 2.64914 0.19361 0.36250 0.08226 0.27465 0.06232 56868.462444 0.000451 0.08418 0.01987 0.97436 0 4.03557 0.26296 3.08894 0.20128 0.33971 0.07708 0.26020 0.05904 56868.463297 0.000402 0.12194 0.02857 0.96403 0 3.31144 0.25509 2.54316 0.19590 0.40380 0.08935 0.31010 0.06862 56868.464041 0.000341 0.13649 0.03174 0.94068 0 3.62820 0.29145 2.77660 0.22304 0.49521 0.10806 0.37901 0.08271 56868.464993 0.000611 0.16599 0.02539 0.97156 0 3.88749 0.22616 2.94497 0.17128 0.64528 0.09127 0.48862 0.06910 56868.465913 0.000310 0.14419 0.03374 0.99065 0 3.58743 0.30278 2.75336 0.23238 0.51729 0.11288 0.39689 0.08661 56868.466720 0.000498 0.07709 0.01843 0.97674 0 3.95731 0.25211 3.01257 0.19194 0.30507 0.07030 0.23234 0.05351 56868.467600 0.000382 0.10990 0.02625 0.96970 0 3.67015 0.27413 2.81115 0.20998 0.40334 0.09152 0.30898 0.07011 56868.468402 0.000420 0.08321 0.01964 0.97931 0 4.43378 0.28799 3.37492 0.21919 0.36892 0.08370 0.27852 0.06320 56868.469116 0.000295 0.15827 0.03820 0.99020 0 3.30356 0.29990 2.50794 0.22762 0.52286 0.11692 0.39670 0.08870 56868.469811 0.000399 0.10093 0.02404 0.98551 0 3.81501 0.27711 2.88783 0.20969 0.38505 0.08736 0.29081 0.06599 56868.470855 0.000645 0.13941 0.02331 0.96861 0 3.66561 0.21338 2.78270 0.16196 0.51101 0.08010 0.38924 0.06101 56868.471804 0.000304 0.15071 0.03621 0.96190 0 3.43471 0.30212 2.62656 0.23103 0.51765 0.11575 0.39670 0.08870 56868.472505 0.000396 0.10145 0.02450 0.96350 0 3.87580 0.28260 2.91250 0.21237 0.39322 0.09054 0.29571 0.06810
