/* ** ** 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 60029.015161 0.000298 0.15725 0.01225 0.98058 0 26.84803 0.76364 24.93940 0.70935 4.22179 0.30625 3.92151 0.28447 60029.015783 0.000324 0.15026 0.01165 0.99107 0 25.51734 0.73329 23.71326 0.68144 3.83429 0.27618 3.56312 0.25665 60029.016420 0.000312 0.14066 0.01097 0.99074 0 28.37443 0.77749 26.21862 0.71837 3.99110 0.29134 3.68554 0.26900 60029.017048 0.000315 0.13929 0.01075 0.98165 0 28.76768 0.77581 26.58818 0.71698 4.00719 0.28964 3.69897 0.26738 60029.017644 0.000281 0.17209 0.01352 1.00000 0 25.51321 0.78354 23.71050 0.72817 4.39056 0.31737 4.08031 0.29495 60029.018202 0.000278 0.16815 0.01318 0.97917 0 26.97429 0.80198 24.89457 0.74005 4.53561 0.32881 4.18922 0.30361 60029.018824 0.000344 0.13308 0.01024 0.99160 0 27.54986 0.72192 25.33457 0.66385 3.66645 0.26528 3.37353 0.24408 60029.019464 0.000295 0.15475 0.01182 0.99020 0 27.76988 0.78458 25.64022 0.72450 4.29752 0.30498 3.96980 0.28172 60029.020118 0.000359 0.12717 0.00983 0.99194 0 27.09760 0.69749 25.04241 0.64459 3.44603 0.25126 3.18753 0.23245 60029.020812 0.000336 0.12914 0.01001 0.99138 0 28.40714 0.74420 26.39824 0.69157 3.66864 0.26754 3.40927 0.24862 60029.021457 0.000310 0.15384 0.01172 1.00000 0 26.34942 0.74244 24.47946 0.68975 4.05363 0.28695 3.76592 0.26659 60029.022065 0.000298 0.15462 0.01210 0.99029 0 26.75235 0.76092 24.85875 0.70706 4.13639 0.30165 3.84379 0.28031 60029.022664 0.000301 0.14920 0.01140 1.00000 0 28.01623 0.77669 25.88165 0.71754 4.17995 0.29768 3.85801 0.27477 60029.023295 0.000330 0.13125 0.00999 0.99123 0 28.81814 0.74613 26.78257 0.69342 3.78235 0.27076 3.51528 0.25164 60029.023954 0.000330 0.15995 0.01148 1.00000 0 27.91988 0.73345 25.94181 0.68149 4.46588 0.29838 4.14955 0.27724
