/* ** ** 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 56183.518654 0.000703 6.98663 1.46966 0.97531 0 0.27330 0.05401 0.23859 0.04715 1.90945 0.13762 1.66697 0.12015 56183.519951 0.000593 11.08382 2.94821 0.99512 0 0.20410 0.05232 0.17818 0.04568 2.26216 0.16047 1.97489 0.14009 56183.521068 0.000524 8.35299 1.90221 0.98895 0 0.30404 0.06574 0.26543 0.05739 2.53965 0.18153 2.21713 0.15848 56183.522607 0.001016 9.25357 1.64754 0.98274 0 0.24812 0.04207 0.21661 0.03673 2.29595 0.12469 2.00438 0.10886 56183.709669 0.000605 4.72066 1.67315 0.92823 0 0.65076 0.21099 0.10810 0.03505 3.07203 0.43988 0.51030 0.07307 56183.710734 0.000454 9.71694 6.37812 0.92994 0 0.24355 0.15316 0.04046 0.02544 2.36660 0.44515 0.39312 0.07394 56183.711799 0.000611 16.42278 9.76462 0.92417 0 0.18943 0.10937 0.03147 0.01817 3.11091 0.44203 0.51676 0.07343 56183.713480 0.001071 6.57453 2.05238 0.92703 0 0.43827 0.12783 0.07280 0.02123 2.88143 0.32057 0.47864 0.05325
