/* ** ** Swift/XRT hardness ratio for Mrk 421. ** 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 56029.331327 0.000894 0.10530 0.00798 0.99353 0 13.73708 0.31934 12.21143 0.28387 1.44645 0.10441 1.28710 0.09287 56029.332965 0.000744 0.12456 0.00959 0.99611 0 13.84333 0.35392 12.33434 0.31534 1.72429 0.12526 1.53632 0.11160 56029.334484 0.000770 0.12360 0.00956 0.99248 0 13.46946 0.33972 11.99714 0.30258 1.66479 0.12176 1.48278 0.10844 56029.335969 0.000715 0.13730 0.01054 0.99190 0 13.25798 0.35303 11.80703 0.31440 1.82033 0.13100 1.62099 0.11666 56029.337459 0.000775 0.12459 0.00966 0.99254 0 13.26751 0.34027 11.81100 0.30291 1.65303 0.12090 1.47163 0.10763 56029.338969 0.000735 0.13423 0.01016 0.98819 0 13.35991 0.35089 11.89719 0.31247 1.79324 0.12733 1.59692 0.11339 56029.340503 0.000799 0.12259 0.00931 0.98551 0 13.36484 0.33556 11.90526 0.29892 1.63841 0.11742 1.45949 0.10460 56029.342172 0.000871 0.11826 0.00856 0.99336 0 14.08858 0.32948 12.54307 0.29333 1.66610 0.11418 1.48342 0.10166
