/* ** ** 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 58523.244412 0.000266 0.15618 0.01188 1.00000 0 29.88178 0.83817 28.06148 0.78711 4.66686 0.33000 4.38257 0.30990 58523.245008 0.000330 0.13327 0.01023 0.98246 0 28.16285 0.73601 26.44726 0.69118 3.75328 0.27083 3.52465 0.25433 58523.245651 0.000312 0.13572 0.01031 1.00000 0 29.03903 0.76788 27.27007 0.72111 3.94116 0.28080 3.70108 0.26369 58523.246270 0.000307 0.13664 0.01033 1.00000 0 29.68305 0.78301 27.87486 0.73531 4.05577 0.28751 3.80871 0.26999 58523.246878 0.000301 0.14522 0.01127 1.00000 0 27.72933 0.76720 26.04015 0.72046 4.02688 0.29205 3.78158 0.27426 58523.247500 0.000321 0.13721 0.01036 0.99099 0 28.26746 0.74849 26.54550 0.70290 3.87870 0.27427 3.64242 0.25756 58523.248110 0.000289 0.15273 0.01180 0.99000 0 27.94243 0.78282 26.24027 0.73514 4.26769 0.30715 4.00771 0.28844 58523.248848 0.000448 0.13444 0.00876 0.98873 0 28.29915 0.63387 26.57526 0.59526 3.80455 0.23281 3.57279 0.21863
