/* ** ** 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 57760.461631 0.000610 0.40196 0.10181 0.97619 1 1.56416 0.21354 0.53064 0.07240 0.62873 0.13413 0.21464 0.04576 57760.462706 0.000465 0.53934 0.15377 1.00000 1 1.41198 0.24975 0.46446 0.08214 0.76153 0.17029 0.25000 0.05590 57760.463911 0.000741 0.30279 0.07566 0.96078 1 1.71920 0.20929 0.56464 0.06873 0.52055 0.11360 0.17143 0.03741 57760.465262 0.000610 0.41682 0.11343 1.00000 1 1.38761 0.20920 0.45129 0.06803 0.57838 0.13104 0.18815 0.04262 57760.466570 0.000697 0.29560 0.07626 1.00000 1 1.71325 0.21594 0.56455 0.07114 0.50644 0.11400 0.16565 0.03728 57760.468443 0.001177 0.18981 0.04666 1.00000 1 1.57677 0.15597 0.51967 0.05140 0.29929 0.06736 0.09816 0.02209 57760.470898 0.001278 0.38122 0.07220 0.96379 1 1.43680 0.14282 0.47828 0.04754 0.54774 0.08830 0.18278 0.02946
