/* ** ** Swift/XRT hardness ratio for PG 1553+113. ** 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 57942.502738 0.000064 0.26188 0.16904 0.91123 0 1.32419 0.38226 1.14458 0.33041 0.34678 0.20022 0.29974 0.17306 57942.503992 0.001177 0.20101 0.04964 1.00000 1 1.02331 0.10369 0.48876 0.04951 0.20569 0.04632 0.09815 0.02209 57942.506302 0.001133 0.23429 0.05804 0.94872 1 0.97220 0.10355 0.46300 0.04931 0.22778 0.05094 0.10811 0.02417 57942.508292 0.000857 0.24326 0.06087 1.00000 1 1.17657 0.13201 0.55966 0.06278 0.28621 0.06402 0.13559 0.03032 57942.510064 0.000915 0.23255 0.05654 0.96825 1 1.26713 0.13554 0.59493 0.06361 0.29468 0.06434 0.13771 0.03005 57942.512257 0.001278 0.18796 0.04481 0.97727 1 1.09057 0.10465 0.51708 0.04961 0.20498 0.04473 0.09768 0.02131 57942.516469 0.002934 0.14566 0.02510 0.99389 1 1.11189 0.06916 0.53139 0.03305 0.16196 0.02603 0.07746 0.01244
