/* ** ** 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 59704.620886 0.000611 0.13188 0.01009 0.99526 0 15.58343 0.40658 14.32872 0.37382 2.05509 0.14783 1.88991 0.13595 59704.622165 0.000668 0.12626 0.00968 0.98701 0 14.82987 0.37927 13.73684 0.35132 1.87237 0.13535 1.73436 0.12538 59704.623453 0.000619 0.14148 0.01083 0.97664 0 14.54309 0.39448 13.47100 0.36540 2.05755 0.14728 1.90588 0.13642 59704.624712 0.000639 0.13411 0.01014 0.99095 0 14.74860 0.38766 13.66108 0.35908 1.97791 0.14020 1.83207 0.12986 59704.625863 0.000512 0.15767 0.01231 1.00000 0 15.22026 0.44066 14.09791 0.40816 2.39974 0.17393 2.22278 0.16111 59704.626992 0.000616 0.13547 0.01048 0.97183 0 15.16846 0.40286 14.04979 0.37315 2.05487 0.14928 1.90332 0.13827 59704.628236 0.000628 0.14170 0.01083 0.99539 0 14.02993 0.38149 12.99576 0.35337 1.98808 0.14197 1.84154 0.13151 59704.630036 0.001172 0.14094 0.00781 0.98025 0 15.00421 0.28839 13.89817 0.26714 2.11463 0.10988 1.95875 0.10178
