/* ** ** 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 56105.196333 0.000521 12.95663 3.58510 1.00000 0 0.19912 0.05322 0.16998 0.04543 2.57993 0.18472 2.20758 0.15806 56105.197346 0.000492 10.34640 2.54742 0.98824 0 0.26734 0.06301 0.22968 0.05414 2.76605 0.19686 2.37790 0.16924 56105.198422 0.000584 9.04934 2.08039 0.97525 0 0.25659 0.05599 0.22026 0.04807 2.32199 0.16796 1.99345 0.14419 56105.199510 0.000503 11.72610 3.10212 0.99358 0 0.22934 0.05843 0.19716 0.05023 2.68931 0.19178 2.31313 0.16495 56105.325483 0.000503 13.29201 3.67931 0.98276 0 0.20439 0.05463 0.17420 0.04656 2.71671 0.19553 2.30719 0.16603 56105.326600 0.000613 17.58658 5.60366 0.98585 0 0.12630 0.03922 0.10793 0.03351 2.22121 0.15832 1.90372 0.13569 56105.327757 0.000544 10.14786 2.49988 0.97340 0 0.24825 0.05851 0.21337 0.05029 2.51921 0.18042 2.16505 0.15506 56105.328856 0.000556 11.10135 2.92239 0.99479 0 0.21889 0.05546 0.18794 0.04762 2.42993 0.17358 2.08485 0.14893 56105.329921 0.000509 8.54721 1.92205 0.98295 0 0.31551 0.06727 0.27039 0.05765 2.69672 0.19279 2.30691 0.16490 56105.331001 0.000570 10.15363 2.54295 0.98985 0 0.23429 0.05621 0.19945 0.04785 2.37891 0.17094 2.02609 0.14557 56105.332112 0.000541 8.81797 2.00735 0.96257 0 0.29521 0.06386 0.25300 0.05473 2.60313 0.18463 2.23269 0.15833 56105.333124 0.000472 9.30355 2.18241 0.98773 0 0.31363 0.07013 0.26890 0.06013 2.91788 0.20680 2.49066 0.17651 56105.334189 0.000593 7.88259 1.70453 0.98049 0 0.29543 0.06031 0.25173 0.05138 2.32875 0.16610 1.98391 0.14149 56105.335387 0.000605 9.56378 2.05753 0.98086 0 0.29210 0.05995 0.24983 0.05126 2.79359 0.18032 2.38384 0.15385
