/* ** ** 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 55969.196192 0.000668 7.97724 1.75046 0.97835 0 0.25944 0.05385 0.22336 0.04636 2.06966 0.14726 1.77804 0.12650 55969.197572 0.000712 8.49464 1.89513 0.95935 0 0.22919 0.04843 0.19714 0.04166 1.94693 0.13936 1.67951 0.12022 55969.198958 0.000674 13.10213 3.64858 0.96996 0 0.15626 0.04206 0.13414 0.03609 2.04735 0.14611 1.75859 0.12550 55969.200364 0.000732 9.77342 2.34856 0.96838 0 0.19239 0.04414 0.16549 0.03797 1.88032 0.13440 1.62001 0.11578 55969.201823 0.000726 10.99928 2.84196 0.97211 0 0.17097 0.04244 0.14784 0.03670 1.88050 0.13488 1.62604 0.11663 55969.203258 0.000709 8.74841 2.01903 0.97551 0 0.21881 0.04797 0.18776 0.04117 1.91425 0.13817 1.65106 0.11916 55969.204635 0.000668 9.64462 2.38790 0.98268 0 0.21009 0.04978 0.18131 0.04297 2.02621 0.14534 1.74782 0.12537 55969.206105 0.000802 7.61326 1.50377 0.97473 0 0.26773 0.04989 0.23147 0.04313 2.03833 0.13349 1.76227 0.11541
