/* ** ** Swift/XRT hardness ratio for PKS 0537-441. ** 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 55253.655553 0.003806 0.30484 0.07795 0.98855 1 0.12690 0.01574 0.10078 0.01250 0.03868 0.00865 0.03089 0.00691 55253.661624 0.002266 0.73550 0.21736 0.98718 1 0.08916 0.01723 0.07079 0.01368 0.06558 0.01467 0.05195 0.01162 55253.668815 0.004924 0.43021 0.09264 0.97695 1 0.10839 0.01277 0.08670 0.01022 0.04663 0.00840 0.03732 0.00673 55253.768397 0.039157 0.28129 0.06998 0.28311 1 0.09923 0.01115 0.05410 0.00536 0.02791 0.00620 0.01363 0.00267 55253.870280 0.004140 0.27524 0.06779 0.98596 1 0.14647 0.01672 0.10947 0.01249 0.04031 0.00880 0.02989 0.00652
