/* ** ** 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 57355.021978 0.000407 0.18606 0.04556 0.96429 1 6.40287 0.61223 1.57505 0.15059 1.19132 0.26853 0.29408 0.06629 57355.022777 0.000392 0.22904 0.05549 0.96296 1 5.65797 0.59511 1.40389 0.14766 1.29590 0.28280 0.32308 0.07050 57355.023866 0.000697 0.13968 0.03337 0.97917 1 4.86805 0.40972 1.21878 0.10258 0.67995 0.15204 0.17021 0.03806 57355.025072 0.000508 0.14940 0.03589 1.00000 1 6.14399 0.53948 1.53415 0.13470 0.91793 0.20527 0.22857 0.05111 57355.026205 0.000625 0.14347 0.03481 0.95349 1 5.32218 0.45226 1.33673 0.11359 0.76360 0.17354 0.19221 0.04368 57355.027207 0.000378 0.21139 0.05267 0.92308 1 6.19621 0.63317 1.55127 0.15852 1.30984 0.29766 0.32835 0.07462 57355.028006 0.000421 0.22493 0.05438 0.96552 1 5.33938 0.55547 1.33219 0.13859 1.20101 0.26208 0.30000 0.06547 57355.028878 0.000450 0.22869 0.05673 0.96774 1 4.63536 0.49778 1.16537 0.12514 1.06007 0.23704 0.26667 0.05963 57355.029865 0.000537 0.15348 0.03715 0.97297 1 5.73379 0.50540 1.43781 0.12673 0.88002 0.19837 0.22056 0.04972 57355.031129 0.000726 0.12891 0.03017 0.98000 1 5.25617 0.42139 1.32049 0.10586 0.67755 0.14900 0.17021 0.03743 57355.032552 0.000697 0.16763 0.03334 0.92849 1 6.34932 0.47096 1.59091 0.11800 1.06431 0.19642 0.26657 0.04920
