/* ** ** Swift/XRT hardness ratio for 3C 66A. ** 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 54741.344917 0.001946 0.12400 0.02941 0.97761 1 0.66120 0.05218 0.49478 0.03904 0.08199 0.01834 0.06107 0.01366 54741.348766 0.001903 0.13222 0.03148 0.99237 1 0.62321 0.05103 0.46544 0.03811 0.08240 0.01842 0.06154 0.01376 54741.352674 0.002005 0.12168 0.02897 0.98551 1 0.64516 0.05070 0.48149 0.03783 0.07850 0.01765 0.05853 0.01316 54741.355811 0.001133 0.24836 0.06235 0.98718 1 0.56037 0.06396 0.41840 0.04776 0.13917 0.03112 0.10390 0.02323 54741.385648 0.028704 0.12804 0.02158 0.15199 1 0.56865 0.03305 0.41329 0.02400 0.07281 0.01152 0.05327 0.00842
