/* ** ** 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 58492.372071 0.000081 0.35499 0.11979 0.98017 0 4.30418 0.75081 2.52060 0.44055 1.52796 0.44137 0.87583 0.25283 58492.372591 0.000421 0.40715 0.10740 0.96552 1 3.41741 0.48979 0.72382 0.10372 1.39141 0.30813 0.29593 0.06553 58492.373390 0.000378 0.34494 0.08999 1.00000 1 4.29593 0.57721 0.89144 0.11978 1.48185 0.33136 0.30769 0.06880 58492.374479 0.000712 0.24957 0.06290 0.93878 1 3.32202 0.37501 0.68946 0.07783 0.82909 0.18682 0.17268 0.03891 58492.375685 0.000494 0.37446 0.09647 0.94118 1 3.35277 0.45051 0.69644 0.09358 1.25546 0.27597 0.26072 0.05731 58492.376978 0.000799 0.30274 0.06678 0.97162 1 3.22265 0.34734 0.66595 0.07177 0.97562 0.18776 0.20210 0.03889
