/* ** ** 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 56101.759783 0.000616 0.09920 0.02329 0.97653 0 2.63008 0.18605 1.94549 0.13751 0.26090 0.05840 0.19263 0.04307 56101.760897 0.000498 0.13582 0.03237 0.95930 0 2.41063 0.19854 1.78819 0.14727 0.32742 0.07322 0.24283 0.05430 56101.762266 0.000871 0.07319 0.01722 0.97010 0 2.50004 0.15479 1.84971 0.11452 0.18299 0.04153 0.13546 0.03073 56101.763562 0.000425 0.15003 0.03601 0.95238 0 2.56709 0.22369 1.90286 0.16581 0.38515 0.08613 0.28619 0.06399 56101.764725 0.000738 0.09382 0.02195 0.98039 0 2.33164 0.16054 1.71541 0.11810 0.21875 0.04892 0.16027 0.03584 56101.766117 0.000654 0.10372 0.02474 0.98230 0 2.30445 0.16976 1.71470 0.12631 0.23901 0.05422 0.17818 0.04042 56101.767740 0.000969 0.06501 0.01501 0.95821 0 2.62610 0.15150 1.92435 0.11101 0.17073 0.03818 0.12482 0.02791 56101.769777 0.001068 0.07811 0.01534 0.97973 0 2.70250 0.14409 1.98755 0.10596 0.21110 0.03990 0.15516 0.02932 56101.893561 0.000399 0.13666 0.03307 0.97826 0 2.58519 0.21651 2.15192 0.18020 0.35329 0.08021 0.29285 0.06648 56101.894626 0.000666 0.10331 0.02406 0.98696 0 2.18076 0.15747 1.77505 0.12815 0.22530 0.04988 0.18299 0.04051 56101.895992 0.000700 0.09789 0.02292 0.97107 0 2.15199 0.14971 1.74242 0.12121 0.21065 0.04710 0.17050 0.03812 56101.897644 0.000952 0.08576 0.01634 0.98480 0 2.64562 0.14424 2.15978 0.11774 0.22688 0.04143 0.18549 0.03387
