/* ** ** 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 58908.105193 0.000596 0.10668 0.00813 0.99029 0 19.66680 0.45988 18.06215 0.42235 2.09810 0.15211 1.92841 0.13979 58908.106316 0.000527 0.12518 0.00949 1.00000 0 19.07074 0.48324 17.47284 0.44272 2.38724 0.17050 2.18549 0.15608 58908.107456 0.000613 0.10949 0.00832 0.98585 0 18.79326 0.44776 17.23958 0.41071 2.05763 0.14843 1.88924 0.13627 58908.108691 0.000622 0.10942 0.00817 0.98140 0 18.97525 0.44604 17.36669 0.40821 2.07620 0.14718 1.90150 0.13478 58908.109970 0.000657 0.10289 0.00779 0.98678 0 18.70339 0.42974 17.11897 0.39332 1.92445 0.13882 1.76272 0.12714 58908.111235 0.000608 0.11140 0.00833 0.98571 0 19.09039 0.45358 17.40570 0.41350 2.12671 0.15074 1.93824 0.13739 58908.112352 0.000509 0.13492 0.01020 1.00000 0 18.38910 0.48438 16.89298 0.44495 2.48109 0.17587 2.27964 0.16159 58908.113700 0.000839 0.11501 0.00724 0.98621 0 19.15872 0.38652 17.49678 0.35298 2.20350 0.13142 2.01294 0.12003
