/* ** ** 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 55985.569975 0.000634 7.52700 1.61958 0.99087 0 0.28880 0.05868 0.24503 0.04979 2.17380 0.15395 1.84392 0.13058 55985.571234 0.000625 6.86956 1.40189 0.97222 0 0.32265 0.06164 0.27503 0.05255 2.21648 0.15898 1.88935 0.13551 55985.572417 0.000558 9.64395 2.33778 0.97409 0 0.25786 0.05970 0.21815 0.05051 2.48679 0.17856 2.10265 0.15097 55985.573575 0.000599 9.82762 2.36191 0.99517 0 0.23024 0.05282 0.19620 0.04501 2.26271 0.16204 1.92865 0.13812 55985.574854 0.000680 7.83357 1.70136 0.96596 0 0.26243 0.05378 0.22176 0.04545 2.05579 0.14785 1.73903 0.12505 55985.576179 0.000645 11.67392 3.08970 0.98655 0 0.18291 0.04660 0.15374 0.03918 2.13533 0.15309 1.79925 0.12899 55985.577449 0.000625 10.79510 2.70197 0.97222 0 0.20617 0.04942 0.17499 0.04195 2.22558 0.16013 1.88424 0.13556 55985.578659 0.000584 12.06200 3.30681 0.96535 0 0.20194 0.05348 0.17007 0.04507 2.43581 0.17277 2.04920 0.14534 55985.579897 0.000654 7.71505 1.56574 0.97788 0 0.32006 0.06136 0.26898 0.05156 2.46930 0.16448 2.07632 0.13831
