/* ** ** 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 55857.759221 0.000339 0.16665 0.03841 0.94872 0 2.77455 0.24308 2.39841 0.21013 0.46238 0.09859 0.39706 0.08465 55857.759872 0.000312 0.20271 0.04970 0.93519 0 2.28825 0.23013 1.96743 0.19786 0.46385 0.10373 0.39670 0.08870 55857.760485 0.000301 0.17054 0.04128 0.97115 0 2.67665 0.24804 2.32579 0.21552 0.45647 0.10207 0.39670 0.08870 55857.761452 0.000666 0.18403 0.02875 0.97391 0 2.78543 0.17430 2.40082 0.15023 0.51259 0.07337 0.44246 0.06333 55857.762418 0.000301 0.16566 0.04059 0.97115 0 2.77649 0.25647 2.36812 0.21873 0.45996 0.10439 0.39147 0.08886 55857.763072 0.000353 0.14215 0.03451 0.95902 0 2.78502 0.23925 2.38173 0.20459 0.39588 0.08989 0.33794 0.07671 55857.763778 0.000353 0.12757 0.03071 0.95902 0 3.09468 0.24744 2.64470 0.21145 0.39478 0.08964 0.33794 0.07671 55857.764571 0.000440 0.10815 0.02548 0.96711 0 2.94720 0.21837 2.51485 0.18632 0.31873 0.07128 0.27256 0.06095 55857.765375 0.000365 0.15369 0.03692 0.95238 0 2.53600 0.22227 2.17236 0.19037 0.38977 0.08716 0.33389 0.07466 55857.766047 0.000307 0.21444 0.05175 1.00000 0 2.17294 0.22386 1.85180 0.19078 0.46596 0.10168 0.39689 0.08661 55857.767088 0.000735 0.17441 0.02702 0.94882 0 2.76847 0.16391 2.34862 0.13905 0.48284 0.06912 0.41125 0.05886 55857.768234 0.000411 0.19025 0.03991 0.95775 0 2.46493 0.20583 2.09583 0.17499 0.46894 0.09025 0.39772 0.07654 55857.769256 0.000611 0.17146 0.03096 0.97156 0 2.40748 0.16700 2.04373 0.14176 0.41279 0.06880 0.35181 0.05863
