/* ** ** 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 58294.205925 0.000666 0.16601 0.01284 0.97826 0 11.65850 0.33815 10.62238 0.30808 1.93541 0.13872 1.76446 0.12644 58294.207215 0.000625 0.18413 0.01437 0.99537 0 10.88312 0.33576 10.02863 0.30939 2.00387 0.14360 1.84653 0.13232 58294.208480 0.000639 0.17256 0.01323 0.98190 0 11.61214 0.34457 10.70010 0.31751 2.00377 0.14169 1.84639 0.13056 58294.209701 0.000582 0.17671 0.01417 1.00000 0 11.84977 0.36263 10.91930 0.33415 2.09400 0.15519 1.92957 0.14300 58294.210899 0.000616 0.17627 0.01355 0.99061 0 11.75387 0.35087 10.83121 0.32333 2.07184 0.14674 1.90920 0.13522 58294.212348 0.000833 0.19622 0.01268 0.99127 0 11.42305 0.30213 10.52637 0.27841 2.24143 0.13219 2.06549 0.12182
