/* ** ** 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 59974.212717 0.000391 0.13346 0.01021 0.98519 0 31.49266 0.83267 22.17037 0.58522 4.20300 0.30164 2.98500 0.21391 59974.213446 0.000339 0.15262 0.01180 1.00000 0 31.58258 0.89157 22.23759 0.62766 4.82022 0.34692 3.39467 0.24426 59974.214146 0.000362 0.15966 0.01242 0.99200 0 28.67421 0.83238 19.96053 0.57942 4.57808 0.33026 3.18688 0.22991 59974.214896 0.000388 0.14504 0.01148 0.97761 0 29.30877 0.81351 20.40875 0.56649 4.25107 0.31509 2.96068 0.21941 59974.215636 0.000353 0.15855 0.01243 0.98361 0 29.64906 0.85149 20.69381 0.59428 4.70083 0.34276 3.27929 0.23913 59974.216337 0.000347 0.15203 0.01192 1.00000 0 30.71655 0.87321 21.46247 0.61010 4.66998 0.34135 3.26259 0.23855 59974.217124 0.000440 0.12468 0.00962 1.00000 0 29.77149 0.76321 20.86359 0.53483 3.71200 0.27003 2.60209 0.18925 59974.217997 0.000434 0.12244 0.00931 0.99333 0 31.28007 0.78839 21.89888 0.55187 3.82984 0.27490 2.67906 0.19227 59974.218787 0.000356 0.14401 0.01111 1.00000 0 31.76063 0.87057 22.30558 0.61141 4.57372 0.32995 3.21279 0.23178 59974.219545 0.000402 0.13658 0.01058 0.99281 0 29.82761 0.80225 20.87296 0.56141 4.07377 0.29588 2.85031 0.20701 59974.220324 0.000376 0.15158 0.01185 0.97692 0 28.96228 0.81360 20.44477 0.57423 4.39000 0.32032 3.09854 0.22595 59974.221082 0.000382 0.13936 0.01071 0.98485 0 31.71771 0.84450 22.04505 0.58693 4.42033 0.31849 3.07194 0.22136 59974.222187 0.000723 0.14466 0.00789 0.99200 0 31.04641 0.60402 21.90023 0.42605 4.49111 0.22874 3.16934 0.16143
