/* ** ** Swift/XRT hardness ratio for PG 1553+113. ** 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 56746.467223 0.000631 0.19361 0.05076 0.98624 0 1.08445 0.11381 0.89914 0.09437 0.20996 0.05045 0.17480 0.04199 56746.468615 0.000761 0.18283 0.04468 0.99240 0 1.01103 0.09969 0.84216 0.08302 0.18484 0.04133 0.15351 0.03433 56746.470045 0.000668 0.19566 0.04673 0.96970 0 1.15189 0.11176 0.95946 0.09309 0.22538 0.04918 0.18781 0.04098 56746.471587 0.000874 0.13473 0.03213 0.98675 0 1.19580 0.09923 0.99664 0.08270 0.16111 0.03602 0.13445 0.03006 56746.473259 0.000799 0.13241 0.03244 0.97826 0 1.31175 0.11063 1.09355 0.09223 0.17369 0.03995 0.14472 0.03328 56746.474535 0.000477 0.27215 0.06870 0.97576 0 1.09251 0.12797 0.91462 0.10713 0.29733 0.06648 0.24886 0.05565 56746.475953 0.000940 0.15455 0.03823 0.97846 0 0.95117 0.08662 0.79498 0.07239 0.14700 0.03381 0.12287 0.02826 56746.477649 0.000755 0.18240 0.04438 0.95402 0 1.05406 0.10111 0.88204 0.08461 0.19226 0.04299 0.16091 0.03598
