/* ** ** 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 55963.369104 0.000773 11.12157 2.86727 0.95131 0 0.17999 0.04458 0.14263 0.03531 2.00180 0.14311 1.56324 0.11167 55963.370614 0.000738 13.85801 4.05573 0.95686 0 0.15241 0.04322 0.11604 0.03292 2.11215 0.15267 1.61043 0.11640 55963.372171 0.000813 8.69038 2.00102 0.95730 0 0.22517 0.04930 0.17081 0.03740 1.95685 0.13944 1.48352 0.10571 55963.373716 0.000732 9.31824 2.22311 0.94466 0 0.23366 0.05316 0.17774 0.04045 2.17730 0.15628 1.65896 0.11907 55963.375163 0.000715 13.38581 3.85557 0.97166 0 0.16102 0.04490 0.12225 0.03408 2.15545 0.15558 1.63941 0.11832 55963.376639 0.000755 16.06976 4.77660 0.97701 0 0.12933 0.03734 0.09893 0.02856 2.07836 0.14719 1.58652 0.11235 55963.378965 0.001571 8.14556 1.30192 0.96685 0 0.23376 0.03535 0.17770 0.02688 1.90408 0.09852 1.44764 0.07489
