/* ** ** 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 57402.204408 0.000295 0.15038 0.01161 0.99020 0 28.59243 0.79179 26.00557 0.72013 4.29982 0.30988 3.91135 0.28189 57402.205013 0.000310 0.13830 0.01051 1.00000 0 30.19469 0.80132 27.19202 0.72162 4.17598 0.29727 3.76132 0.26773 57402.205597 0.000275 0.15396 0.01178 1.00000 0 30.08283 0.84259 27.51774 0.77075 4.63147 0.32966 4.23644 0.30154 57402.206176 0.000304 0.14205 0.01077 1.00000 0 29.52362 0.79406 26.90216 0.72355 4.19380 0.29721 3.82157 0.27083 57402.206775 0.000295 0.14548 0.01148 1.00000 0 28.65560 0.79748 26.16566 0.72819 4.16884 0.30773 3.80412 0.28082 57402.207377 0.000307 0.13828 0.01059 0.99057 0 30.24618 0.80287 27.50624 0.73011 4.18244 0.30055 3.80620 0.27348 57402.207967 0.000284 0.15115 0.01179 1.00000 0 29.14335 0.81860 26.49528 0.74419 4.40496 0.32056 4.00241 0.29122 57402.208546 0.000295 0.14508 0.01099 1.00000 0 29.71898 0.80984 27.06444 0.73747 4.31172 0.30489 3.92811 0.27776 57402.209107 0.000266 0.16631 0.01273 0.98913 0 29.03232 0.84114 26.51193 0.76812 4.82839 0.34218 4.40951 0.31249 57402.209654 0.000281 0.15603 0.01192 0.98969 0 29.55156 0.83051 26.86503 0.75497 4.61081 0.32752 4.18608 0.29731 57402.210233 0.000298 0.14172 0.01088 0.99029 0 30.18631 0.81322 27.43347 0.73904 4.27810 0.30756 3.89264 0.27981 57402.210806 0.000275 0.15206 0.01173 1.00000 0 30.04669 0.84015 27.48592 0.76854 4.56887 0.32842 4.17947 0.30043 57402.211353 0.000272 0.15460 0.01183 0.97872 0 31.16388 0.86572 28.32194 0.78673 4.81794 0.34364 4.38108 0.31251 57402.211900 0.000275 0.15387 0.01190 0.98947 0 29.85725 0.83867 27.31320 0.76721 4.59407 0.33109 4.20262 0.30288 57402.212467 0.000292 0.14801 0.01136 0.99010 0 29.64439 0.81463 26.95237 0.74065 4.38762 0.31458 3.99053 0.28611 57402.213051 0.000292 0.14639 0.01116 1.00000 0 29.75517 0.81287 27.22087 0.74363 4.35575 0.31004 3.98477 0.28363 57402.213589 0.000246 0.18300 0.01423 0.98824 0 28.29206 0.87333 25.88252 0.79895 5.17731 0.36958 4.73639 0.33811 57402.214064 0.000229 0.18714 0.01456 0.98734 0 29.81360 0.92081 27.25780 0.84187 5.57935 0.39828 5.10073 0.36412 57402.214755 0.000463 0.15579 0.00940 0.99375 0 29.59757 0.64649 26.77999 0.58494 4.61096 0.25940 4.16897 0.23450
