/* ** ** 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 56063.092854 0.000935 0.51484 0.04538 0.98142 0 2.86800 0.14771 2.42899 0.12510 1.47655 0.10560 1.25107 0.08948 56063.094738 0.000949 0.51289 0.04507 0.98171 0 2.83045 0.14520 2.40705 0.12348 1.45171 0.10356 1.23446 0.08806 56063.096696 0.001010 0.45659 0.03964 0.97994 0 2.96451 0.14355 2.52237 0.12214 1.35357 0.09755 1.15167 0.08300 56063.098716 0.001010 0.47381 0.04113 0.98281 0 2.87129 0.14163 2.44280 0.12049 1.36046 0.09718 1.15756 0.08268 56063.100727 0.001001 0.51128 0.04491 0.96532 0 2.73935 0.14071 2.33072 0.11972 1.40059 0.09979 1.19146 0.08489 56063.102926 0.001198 0.54922 0.04287 0.96618 0 2.77428 0.12858 2.35936 0.10935 1.52368 0.09569 1.29567 0.08137
