/* ** ** 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 58242.924434 0.000897 0.09569 0.00721 0.97742 0 14.95846 0.32996 13.60341 0.30006 1.43142 0.10314 1.30389 0.09396 58242.926205 0.000874 0.09502 0.00737 0.98675 0 14.90758 0.33232 13.67859 0.30492 1.41645 0.10525 1.29968 0.09657 58242.927846 0.000767 0.10900 0.00812 0.99623 0 15.17511 0.35722 13.92372 0.32777 1.65407 0.11696 1.51768 0.10732 58242.929443 0.000830 0.10537 0.00794 0.98258 0 14.63869 0.33851 13.43084 0.31058 1.54246 0.11057 1.41520 0.10145 58242.931110 0.000836 0.10296 0.00773 0.98962 0 14.74876 0.33722 13.53278 0.30942 1.51849 0.10862 1.39329 0.09967 58242.932788 0.000842 0.10374 0.00784 0.97251 0 14.66591 0.33560 13.45682 0.30794 1.52147 0.10963 1.39604 0.10060 58242.934512 0.000883 0.09523 0.00709 0.99344 0 15.20263 0.33310 13.94940 0.30564 1.44767 0.10303 1.32834 0.09454
