/* ** ** Swift/XRT hardness ratio for Cen A. ** 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 56088.088903 0.000558 12.77392 3.42063 0.97927 0 0.19397 0.05008 0.16602 0.04287 2.47770 0.17591 2.11813 0.15038 56088.089968 0.000506 15.17962 4.51826 0.97714 0 0.17872 0.05163 0.15308 0.04423 2.71296 0.19439 2.31567 0.16591 56088.091044 0.000570 9.54131 2.26561 0.96954 0 0.25551 0.05789 0.21877 0.04957 2.43787 0.17329 2.08792 0.14841 56088.092074 0.000460 13.35894 3.75978 0.99371 0 0.22040 0.06002 0.18889 0.05144 2.94425 0.20928 2.52400 0.17941 56088.093081 0.000547 8.24654 1.85405 0.99471 0 0.29904 0.06376 0.25624 0.05463 2.46605 0.17598 2.11375 0.15084 56088.094216 0.000582 7.84224 1.76498 0.98010 0 0.29942 0.06389 0.25669 0.05477 2.34812 0.16801 2.01243 0.14399 56088.095385 0.000587 10.84962 2.74324 0.98030 0 0.21811 0.05294 0.18682 0.04535 2.36639 0.16760 2.02711 0.14357 56088.096525 0.000553 7.44965 1.61045 0.98953 0 0.33018 0.06740 0.28282 0.05773 2.45974 0.17507 2.10753 0.15000 56088.097830 0.000752 13.09437 3.19285 0.98846 0 0.18504 0.04365 0.15847 0.03738 2.42305 0.14978 2.07549 0.12829
