/* ** ** 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 53836.117670 0.001772 0.14178 0.02693 0.98253 1 2.98370 0.20069 0.75095 0.05051 0.42302 0.07514 0.10631 0.01888 53836.447192 0.000162 0.17839 0.05815 0.87831 0 3.53294 0.43557 2.50405 0.30859 0.63022 0.19016 0.44799 0.13507 53836.448366 0.001002 0.15757 0.03815 0.97101 1 3.56686 0.31591 0.75470 0.06684 0.56204 0.12664 0.11857 0.02671 53836.450298 0.000930 0.16966 0.04100 0.96875 1 3.57894 0.32822 0.76202 0.06988 0.60719 0.13577 0.12903 0.02885 53836.452346 0.001118 0.16822 0.03645 0.98408 1 3.69246 0.30813 0.78552 0.06555 0.62113 0.12423 0.13197 0.02639 53836.513838 0.000142 0.11234 0.04491 0.99552 0 3.63901 0.47221 2.50454 0.32493 0.40881 0.15456 0.28745 0.10865 53836.514850 0.000857 0.18363 0.04508 0.98305 1 3.30352 0.32209 0.74499 0.07263 0.60662 0.13668 0.13697 0.03086 53836.516811 0.001104 0.17523 0.04161 1.00000 1 2.78113 0.26058 0.63026 0.05905 0.48734 0.10635 0.11053 0.02412 53836.519019 0.001104 0.18139 0.04201 0.95754 1 2.95557 0.26736 0.66779 0.06041 0.53610 0.11430 0.12092 0.02578 53836.640275 0.000101 0.13916 0.07504 0.97038 0 3.17378 0.62563 1.62755 0.31919 0.44167 0.22167 0.23592 0.11796 53836.641494 0.001104 0.14478 0.03489 0.97368 1 3.36261 0.28746 0.74156 0.06339 0.48683 0.10968 0.10735 0.02419 53836.643615 0.001017 0.15947 0.03850 1.00000 1 3.25594 0.29647 0.71695 0.06528 0.51924 0.11611 0.11429 0.02556 53836.645576 0.000944 0.13771 0.03289 1.00000 1 4.04922 0.33992 0.89389 0.07504 0.55762 0.12469 0.12308 0.02752 53836.647159 0.000639 0.30267 0.07735 0.93182 1 2.89519 0.34931 0.64056 0.07728 0.87628 0.19741 0.19376 0.04365 53836.648728 0.000930 0.16641 0.04054 0.98438 1 3.43612 0.31818 0.76053 0.07043 0.57179 0.12883 0.12610 0.02841 53836.650529 0.000872 0.17324 0.04220 0.95000 1 3.62694 0.33575 0.80594 0.07460 0.62834 0.14157 0.13937 0.03140 53836.653129 0.001729 0.13794 0.02689 0.97869 1 3.36282 0.22950 0.74642 0.05094 0.46387 0.08469 0.10304 0.01881
