/* ** ** 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 59700.639721 0.000674 0.12528 0.00948 0.99142 0 14.99856 0.38201 13.80927 0.35168 1.87907 0.13381 1.73085 0.12326 59700.641058 0.000663 0.12943 0.00986 0.98690 0 14.80979 0.38093 13.64683 0.35098 1.91682 0.13746 1.76542 0.12661 59700.642415 0.000694 0.11137 0.00852 1.00000 0 16.02599 0.38861 14.74839 0.35762 1.78488 0.12959 1.64223 0.11923 59700.643815 0.000706 0.11974 0.00907 0.98770 0 15.15297 0.37678 13.81199 0.34339 1.81442 0.12983 1.65312 0.11829 59700.645230 0.000709 0.11562 0.00893 0.99184 0 15.26165 0.37772 13.90247 0.34411 1.76460 0.12910 1.60786 0.11761 59700.646648 0.000709 0.11960 0.00910 0.99184 0 14.98642 0.37832 13.65027 0.34456 1.79239 0.12862 1.63127 0.11703 59700.647999 0.000642 0.13221 0.01005 0.98649 0 15.35477 0.40233 13.82636 0.36227 2.03010 0.14490 1.82834 0.13050 59700.649278 0.000637 0.12993 0.01001 0.97273 0 15.46916 0.40353 14.14646 0.36899 2.00995 0.14562 1.83904 0.13322 59700.650988 0.001073 0.11823 0.00727 0.98383 0 15.34959 0.30873 14.03791 0.28237 1.81481 0.10539 1.66002 0.09641
