/* ** ** 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 55722.039981 0.000587 0.11378 0.02689 0.97537 0 2.79667 0.21404 1.77135 0.13557 0.31821 0.07116 0.20236 0.04525 55722.041254 0.000686 0.09153 0.02170 0.96203 0 2.98387 0.20512 1.89076 0.12995 0.27311 0.06196 0.17348 0.03936 55722.042683 0.000744 0.07247 0.01678 0.96887 0 3.45251 0.20847 2.21439 0.13371 0.25019 0.05595 0.16091 0.03598 55722.044986 0.001560 0.07048 0.01169 0.97182 0 3.29232 0.14099 2.11581 0.09056 0.23206 0.03717 0.14916 0.02388 55722.308857 0.000498 0.09420 0.02236 0.96512 0 2.91953 0.20260 2.52664 0.17533 0.27501 0.06242 0.23818 0.05406 55722.309664 0.000310 0.15902 0.03889 0.96262 0 2.78032 0.25325 2.41364 0.21985 0.44211 0.10036 0.38386 0.08713 55722.310402 0.000428 0.11676 0.02763 0.99324 0 2.73054 0.21163 2.32685 0.18036 0.31881 0.07129 0.27256 0.06095 55722.311284 0.000454 0.09350 0.02219 0.99363 0 3.15836 0.21919 2.70481 0.18770 0.29531 0.06703 0.25345 0.05753 55722.312112 0.000373 0.12106 0.02905 0.96899 0 3.09724 0.24126 2.61020 0.20332 0.37494 0.08509 0.31630 0.07180 55722.312940 0.000454 0.10924 0.02575 0.97452 0 2.78609 0.20765 2.39451 0.17846 0.30436 0.06806 0.26187 0.05856 55722.313967 0.000573 0.14040 0.02435 0.97475 0 3.26984 0.20038 2.80848 0.17210 0.45909 0.07448 0.39444 0.06399
