/* ** ** 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 56816.015546 0.000344 0.15413 0.03701 0.96639 0 2.61777 0.22892 2.25089 0.19683 0.40347 0.09022 0.34841 0.07791 56816.016351 0.000460 0.12046 0.02900 0.98742 0 2.41845 0.19305 2.09092 0.16690 0.29133 0.06616 0.25174 0.05717 56816.017329 0.000518 0.09831 0.02282 0.98324 0 2.76426 0.19201 2.39348 0.16624 0.27176 0.06018 0.23595 0.05225 56816.018231 0.000385 0.14539 0.03477 0.96241 0 2.48424 0.21076 2.15084 0.18247 0.36118 0.08077 0.31302 0.06999 56816.019039 0.000422 0.12458 0.03003 0.98630 0 2.53406 0.20505 2.20372 0.17832 0.31569 0.07169 0.27447 0.06233 56816.019988 0.000527 0.08514 0.01984 0.96154 0 3.09406 0.20232 2.68915 0.17584 0.26344 0.05891 0.22895 0.05120 56816.020960 0.000446 0.11058 0.02547 0.98052 0 2.89815 0.21381 2.51911 0.18585 0.32047 0.06993 0.27861 0.06080 56816.021790 0.000385 0.11907 0.02818 0.95489 0 3.05022 0.23609 2.64958 0.20508 0.36320 0.08121 0.31549 0.07054 56816.022575 0.000399 0.11510 0.02804 0.98551 0 2.86681 0.22419 2.49014 0.19473 0.32998 0.07612 0.28663 0.06612 56816.023388 0.000414 0.11493 0.02719 0.97902 0 2.86421 0.22156 2.48933 0.19256 0.32918 0.07361 0.28619 0.06399 56816.024305 0.000503 0.14665 0.02680 0.98851 0 3.18369 0.20870 2.75433 0.18055 0.46689 0.07963 0.40450 0.06898
