/* ** ** Swift/XRT hardness ratio for NRAO 676. ** 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 54873.315594 0.037863 0.74118 0.21415 0.22878 1 0.02962 0.00560 0.01894 0.00358 0.02195 0.00480 0.01406 0.00307 54873.448237 0.039261 0.78741 0.20664 0.28346 1 0.02697 0.00470 0.01725 0.00300 0.02124 0.00417 0.01356 0.00266 54873.582130 0.039397 1.04759 0.27771 0.24528 1 0.02640 0.00499 0.01661 0.00314 0.02766 0.00514 0.01742 0.00324 54873.718512 0.037022 1.23539 0.36248 0.22732 1 0.02215 0.00483 0.01457 0.00318 0.02736 0.00537 0.01795 0.00352 54873.884012 0.072156 1.39252 0.30932 0.21122 1 0.01849 0.00314 0.01332 0.00226 0.02574 0.00368 0.01868 0.00267
