/* ** ** 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 56512.965940 0.000836 0.09964 0.02336 0.96194 0 1.74746 0.12320 1.44192 0.10165 0.17412 0.03893 0.14412 0.03223 56512.967558 0.000781 0.09081 0.02153 0.96667 0 2.02493 0.13845 1.66576 0.11389 0.18389 0.04175 0.15153 0.03438 56512.968952 0.000613 0.12721 0.03067 0.98585 0 1.79783 0.14661 1.48723 0.12128 0.22870 0.05190 0.18923 0.04294 56512.970026 0.000460 0.21873 0.05418 0.98113 0 1.42481 0.15179 1.17458 0.12514 0.31165 0.06969 0.25684 0.05743 56512.971062 0.000576 0.13184 0.03189 0.98995 0 1.84112 0.15399 1.52283 0.12737 0.24274 0.05508 0.20075 0.04555 56512.972665 0.001027 0.08129 0.01891 0.97465 0 1.72499 0.11065 1.42130 0.09117 0.14023 0.03136 0.11580 0.02589 56512.974534 0.000842 0.09834 0.02341 0.97938 0 1.71412 0.12269 1.41404 0.10120 0.16857 0.03827 0.13877 0.03149 56512.975871 0.000483 0.15177 0.03699 0.97605 0 1.93764 0.17247 1.60035 0.14244 0.29408 0.06673 0.24263 0.05506 56512.977170 0.000810 0.10706 0.02459 0.97500 0 1.75161 0.12528 1.43838 0.10287 0.18752 0.04092 0.15410 0.03363 56512.978628 0.000648 0.12682 0.03011 0.95982 0 1.77841 0.14196 1.46962 0.11731 0.22553 0.05043 0.18636 0.04167 56512.980318 0.001042 0.08089 0.01882 0.97222 0 1.71521 0.10982 1.41724 0.09074 0.13875 0.03103 0.11448 0.02560 56512.982089 0.000729 0.12635 0.02932 0.98413 0 1.63009 0.12848 1.34284 0.10581 0.20596 0.04495 0.16964 0.03702 56512.983767 0.000949 0.09363 0.02087 0.97256 0 1.78442 0.11600 1.47579 0.09594 0.16708 0.03562 0.13816 0.02946
