/* ** ** Swift/XRT hardness ratio for 1ES 1218+304. ** 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 55973.387940 0.001133 0.20081 0.04932 0.97436 1 1.56824 0.15890 0.52138 0.05281 0.31491 0.07045 0.10526 0.02354 55973.390177 0.001104 0.20841 0.05114 0.96053 1 1.56992 0.15861 0.52267 0.05280 0.32719 0.07317 0.10959 0.02451 55973.392574 0.001264 0.18428 0.04490 0.98851 1 1.52718 0.14767 0.50596 0.04892 0.28142 0.06293 0.09302 0.02080 55973.394913 0.001075 0.24938 0.06235 0.98649 1 1.35075 0.15106 0.44118 0.04933 0.33685 0.07533 0.10959 0.02451 55973.397977 0.001990 0.26625 0.04836 0.97632 1 1.33018 0.11126 0.43490 0.03637 0.35416 0.05710 0.11591 0.01868
