/* ** ** Swift/XRT hardness ratio for 3C 273. ** 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 57595.084189 0.000969 0.51139 0.04489 0.97612 0 2.76106 0.14107 2.37614 0.12139 1.41199 0.10079 1.21519 0.08674 57595.086145 0.000987 0.47302 0.04085 0.97654 0 2.92545 0.14410 2.53682 0.12495 1.38378 0.09816 1.19990 0.08511 57595.088156 0.001024 0.46773 0.04036 0.99153 0 2.80475 0.13738 2.43082 0.11907 1.31186 0.09320 1.13680 0.08076 57595.090179 0.000998 0.42966 0.03680 0.98841 0 3.12086 0.14666 2.70484 0.12711 1.34089 0.09601 1.16207 0.08321 57595.092175 0.000998 0.41497 0.03521 0.98551 0 3.27038 0.15114 2.82240 0.13043 1.35710 0.09657 1.17196 0.08339 57595.094224 0.001050 0.42918 0.03671 0.98898 0 3.02299 0.14322 2.59321 0.12284 1.29741 0.09238 1.11245 0.07920 57595.096591 0.001317 0.47444 0.03564 0.98681 0 2.92877 0.12550 2.49935 0.10708 1.38951 0.08572 1.18797 0.07328
