/* ** ** 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 56180.658633 0.000457 0.14572 0.02256 0.96835 0 5.13011 0.28029 4.40171 0.24047 0.74756 0.10831 0.64102 0.09284 56180.659690 0.000599 0.11434 0.01714 0.94686 0 5.16952 0.24474 4.45161 0.21074 0.59108 0.08409 0.50839 0.07232 56180.660838 0.000550 0.11780 0.01772 0.96842 0 5.39428 0.26348 4.59236 0.22430 0.63543 0.09041 0.54154 0.07704 56180.661941 0.000553 0.12808 0.01937 0.99476 0 4.75265 0.24367 4.09469 0.20992 0.60871 0.08660 0.52444 0.07461 56180.662979 0.000486 0.13822 0.02101 1.00000 0 5.00680 0.26789 4.29331 0.22969 0.69203 0.09845 0.59312 0.08438 56180.664030 0.000564 0.11534 0.01754 0.99487 0 5.09670 0.24975 4.40633 0.21592 0.58786 0.08463 0.50824 0.07317 56180.665161 0.000567 0.12464 0.01879 0.95918 0 4.96879 0.24770 4.26026 0.21236 0.61930 0.08812 0.53002 0.07540 56180.666275 0.000547 0.12887 0.01959 0.98413 0 4.78998 0.24512 4.13500 0.21160 0.61731 0.08837 0.53291 0.07626 56180.667192 0.000370 0.07051 0.01655 0.97656 0 5.22185 0.31326 4.49025 0.26936 0.36821 0.08356 0.31635 0.07180 56180.668503 0.000940 0.12743 0.01515 0.98154 0 4.59861 0.18479 3.96667 0.15940 0.58600 0.06559 0.50541 0.05657
