/* ** ** 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 58636.945908 0.000234 0.23792 0.01884 0.98765 0 23.98876 0.83245 20.97017 0.72754 5.70748 0.40630 4.98550 0.35488 58636.946386 0.000243 0.22618 0.01831 0.98810 0 24.67669 0.84590 21.04789 0.72143 5.58133 0.40921 4.76974 0.34963 58636.946869 0.000240 0.24224 0.01928 1.00000 0 22.83919 0.81120 19.86364 0.70554 5.53259 0.39394 4.80530 0.34205 58636.947387 0.000272 0.21389 0.01677 1.00000 0 22.52959 0.74817 19.93729 0.66210 4.81895 0.34217 4.26429 0.30278 58636.947902 0.000243 0.26137 0.02080 1.00000 0 20.95397 0.77188 18.32307 0.67488 5.47680 0.38632 4.79370 0.33812 58636.948397 0.000252 0.23389 0.01876 1.00000 0 22.12726 0.77697 19.40769 0.68147 5.17538 0.37332 4.54235 0.32767 58636.948897 0.000249 0.22943 0.01827 1.00000 0 22.97344 0.79629 20.10532 0.69677 5.27086 0.37778 4.61642 0.33080 58636.949433 0.000286 0.19929 0.01567 0.98990 0 23.30134 0.74379 20.54909 0.65595 4.64375 0.33373 4.09562 0.29435 58636.949956 0.000237 0.24976 0.01985 1.00000 0 22.40267 0.81190 19.57779 0.70952 5.59523 0.39566 4.88618 0.34551 58636.950440 0.000246 0.21070 0.01711 1.00000 0 24.82978 0.83331 21.78190 0.73100 5.23156 0.38675 4.58680 0.33895 58636.950917 0.000231 0.26975 0.02187 0.98750 0 21.29749 0.79584 18.63776 0.69640 5.74493 0.41345 5.02770 0.36175 58636.951383 0.000234 0.24240 0.01940 1.00000 0 23.04531 0.81743 20.33080 0.72115 5.58610 0.40089 4.92829 0.35368 58636.951901 0.000284 0.19804 0.01551 0.95918 0 24.29654 0.76286 21.44248 0.67325 4.81164 0.34529 4.24672 0.30477 58636.952454 0.000269 0.21293 0.01679 1.00000 0 22.90321 0.76255 20.12353 0.67004 4.87676 0.34864 4.29049 0.30666 58636.952998 0.000275 0.21102 0.01682 0.97895 0 22.88431 0.75293 20.05206 0.65975 4.82901 0.35070 4.22965 0.30716 58636.953521 0.000249 0.23401 0.01851 1.00000 0 22.61090 0.78203 20.02634 0.69264 5.29116 0.37628 4.68630 0.33325 58636.954048 0.000278 0.19601 0.01529 1.00000 0 24.27139 0.77415 21.19616 0.67606 4.75745 0.33866 4.15458 0.29573 58636.954569 0.000243 0.23428 0.01893 1.00000 0 23.04961 0.81184 20.06514 0.70679 5.40014 0.39277 4.70877 0.34243 58636.955101 0.000289 0.21140 0.01682 1.00000 0 21.37580 0.71715 18.69463 0.62714 4.51883 0.32595 3.95185 0.28508 58636.955654 0.000263 0.21895 0.01743 0.98901 0 22.64972 0.76258 20.05485 0.67521 4.95917 0.35775 4.39094 0.31675 58636.956169 0.000252 0.22173 0.01754 1.00000 0 23.45860 0.79494 20.68276 0.70090 5.20152 0.37178 4.58638 0.32781 58636.956681 0.000260 0.22105 0.01758 1.00000 0 23.41018 0.79363 20.27151 0.68717 5.17479 0.37241 4.48389 0.32269
