/* ** ** 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 59367.916993 0.000709 0.12832 0.00990 0.98776 0 13.72592 0.35795 12.65305 0.32997 1.76135 0.12788 1.62569 0.11803 59367.918391 0.000689 0.12720 0.01011 0.99160 0 14.00224 0.36710 12.77437 0.33491 1.78107 0.13367 1.62863 0.12224 59367.919855 0.000775 0.11802 0.00900 0.97388 0 14.01714 0.34518 12.85826 0.31664 1.65425 0.11936 1.51429 0.10921 59367.921334 0.000703 0.11906 0.00920 0.98765 0 14.95505 0.37392 13.71079 0.34281 1.78054 0.13016 1.63169 0.11925 59367.922676 0.000639 0.13945 0.01074 0.99548 0 14.00311 0.37976 12.89641 0.34970 1.95269 0.14081 1.79650 0.12957 59367.924123 0.000807 0.10917 0.00827 0.99283 0 14.30709 0.33908 13.13254 0.31124 1.56190 0.11237 1.43406 0.10316 59367.925986 0.001056 0.10840 0.00716 0.98356 0 14.66041 0.30149 13.38993 0.27538 1.58914 0.09979 1.45301 0.09123
