/* ** ** Swift/XRT hardness ratio for PKS 1222+216. ** 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 56974.897998 0.004401 0.34827 0.09112 0.99010 1 0.15405 0.02002 0.08000 0.01036 0.05365 0.01218 0.02667 0.00596 56974.906757 0.004358 0.43932 0.09678 0.98117 1 0.17644 0.02157 0.09167 0.01120 0.07751 0.01421 0.04063 0.00744 56974.962124 0.003399 0.43778 0.11726 0.98291 1 0.10009 0.01476 0.07931 0.01169 0.04382 0.00980 0.03478 0.00778 56974.967324 0.001801 0.72365 0.21350 1.00000 1 0.11274 0.02170 0.08926 0.01718 0.08159 0.01824 0.06452 0.01443 56974.973439 0.004314 0.45263 0.09791 0.97070 1 0.11975 0.01444 0.09504 0.01146 0.05420 0.00974 0.04301 0.00773
