/* ** ** 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 57363.928623 0.000320 0.18799 0.04650 0.95455 1 9.06711 0.87235 1.99312 0.19176 1.70455 0.38846 0.37439 0.08531 57363.929582 0.000639 0.19006 0.03210 1.00000 1 9.19544 0.62688 2.02568 0.13810 1.74767 0.27005 0.38621 0.05968 57363.930976 0.000755 0.23030 0.03579 0.94231 1 8.18747 0.54280 1.80339 0.11956 1.88554 0.26500 0.41492 0.05831 57363.932066 0.000334 0.19531 0.04925 1.00000 1 7.89805 0.81610 1.73544 0.17932 1.54256 0.35485 0.33883 0.07795 57363.932778 0.000378 0.19896 0.04916 0.96154 1 7.23649 0.72773 1.59173 0.16007 1.43976 0.32497 0.31724 0.07161 57363.933475 0.000320 0.20999 0.05214 0.95455 1 8.11273 0.83897 1.79640 0.18577 1.70360 0.38452 0.37767 0.08525 57363.934172 0.000378 0.21335 0.04804 0.96154 1 8.12268 0.77221 1.79919 0.17103 1.73295 0.35375 0.38400 0.07838 57363.935000 0.000450 0.15479 0.03756 0.96774 1 7.71061 0.68615 1.71036 0.15220 1.19354 0.26939 0.26437 0.05967 57363.936452 0.001002 0.22469 0.03167 0.96928 1 7.50141 0.45697 1.66083 0.10118 1.68552 0.21427 0.37370 0.04751
