/* ** ** 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 56101.186661 0.000654 12.56425 3.43296 0.97345 0 0.16807 0.04432 0.14388 0.03794 2.11164 0.15123 1.80108 0.12898 56101.187905 0.000590 10.86056 2.76197 0.97059 0 0.21558 0.05265 0.18691 0.04564 2.34127 0.16602 2.02983 0.14394 56101.189121 0.000625 8.50798 1.89781 0.97685 0 0.25633 0.05419 0.22206 0.04694 2.18083 0.15518 1.88840 0.13437 56101.190345 0.000599 15.86182 4.96176 0.97101 0 0.14347 0.04368 0.12396 0.03775 2.27563 0.16322 1.96858 0.14119 56101.191479 0.000535 12.81865 3.57412 0.98378 0 0.19652 0.05295 0.17025 0.04587 2.51913 0.18079 2.17901 0.15638 56101.192584 0.000570 9.49426 2.23880 0.97462 0 0.25431 0.05721 0.22023 0.04954 2.41453 0.17084 2.09147 0.14798 56101.193713 0.000558 11.70864 3.04488 0.97409 0 0.20765 0.05191 0.18008 0.04502 2.43131 0.17411 2.10765 0.15093 56101.194861 0.000590 9.11505 2.18325 0.98529 0 0.24822 0.05670 0.21494 0.04910 2.26257 0.16306 1.96031 0.14128 56101.196025 0.000573 10.02966 2.47078 0.97475 0 0.23728 0.05593 0.20489 0.04829 2.37982 0.17043 2.05305 0.14702 56101.197257 0.000660 9.25209 1.98508 0.97807 0 0.26022 0.05312 0.22363 0.04565 2.40753 0.15901 2.07827 0.13726
