/* ** ** 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 56191.324195 0.000758 11.71253 3.04524 0.98473 0 0.15340 0.03835 0.13191 0.03298 1.79671 0.12821 1.54939 0.11054 56191.325772 0.000813 9.71332 2.37044 0.97509 0 0.17286 0.04031 0.14828 0.03458 1.67907 0.12086 1.44360 0.10391 56191.327294 0.000709 7.91816 1.73858 0.96735 0 0.24779 0.05145 0.21153 0.04394 1.96207 0.14004 1.67671 0.11968 56191.328738 0.000735 8.04262 1.77333 0.93701 0 0.24347 0.05078 0.20734 0.04323 1.95817 0.14000 1.66736 0.11920 56191.330234 0.000761 8.04182 1.77330 0.98099 0 0.22433 0.04678 0.19040 0.03970 1.80406 0.12936 1.53386 0.11000 56191.331794 0.000799 8.40157 1.93895 0.97464 0 0.20645 0.04530 0.17542 0.03848 1.73454 0.12419 1.47317 0.10548 56191.334002 0.001409 9.20317 1.61832 0.97125 0 0.19748 0.03312 0.16690 0.02799 1.81745 0.09609 1.53701 0.08126
