/* ** ** 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 57480.236646 0.000266 0.17394 0.01344 1.00000 0 27.89761 0.83161 25.09530 0.74807 4.85257 0.34586 4.35905 0.31075 57480.237202 0.000289 0.15595 0.01204 0.99000 0 28.45622 0.80452 25.99940 0.73506 4.43766 0.31888 4.05454 0.29135 57480.237728 0.000237 0.19596 0.01554 0.98780 0 27.17700 0.86668 24.78212 0.79031 5.32557 0.38670 4.85662 0.35265 57480.238252 0.000286 0.16326 0.01280 0.98990 0 27.13138 0.79510 24.72419 0.72455 4.42943 0.32206 4.03646 0.29349 57480.238814 0.000275 0.16491 0.01263 1.00000 0 28.20409 0.82182 25.71416 0.74927 4.65113 0.32940 4.24056 0.30032 57480.239369 0.000281 0.17994 0.01411 0.98969 0 25.23948 0.76909 23.00435 0.70099 4.54163 0.32805 4.13951 0.29900 57480.239925 0.000275 0.16693 0.01321 0.98947 0 27.53641 0.80876 25.10572 0.73737 4.59660 0.33776 4.19081 0.30794 57480.240521 0.000321 0.15010 0.01142 1.00000 0 26.37881 0.73868 24.04855 0.67343 3.95934 0.27997 3.60961 0.25524 57480.241134 0.000292 0.15258 0.01194 1.00000 0 28.01713 0.79529 25.53908 0.72495 4.27489 0.31165 3.89673 0.28408 57480.241716 0.000289 0.15472 0.01207 1.00000 0 27.87840 0.79513 25.42540 0.72516 4.31346 0.31320 3.93386 0.28564 57480.242280 0.000275 0.17234 0.01371 0.98947 0 26.54099 0.79608 24.19515 0.72572 4.57404 0.33700 4.16950 0.30720 57480.242844 0.000289 0.15695 0.01228 1.00000 0 27.64001 0.79778 25.20294 0.72744 4.33820 0.31543 3.95573 0.28762 57480.243452 0.000318 0.16871 0.01266 0.98823 0 26.32582 0.74245 24.00331 0.67695 4.44142 0.30893 4.04946 0.28167 57480.303392 0.000347 0.15689 0.01236 0.98333 0 26.40227 0.74761 21.46330 0.60516 4.14217 0.30451 3.31859 0.24255 57480.304022 0.000284 0.16588 0.01301 1.00000 0 28.27102 0.83296 24.31701 0.71642 4.68957 0.34098 4.03674 0.29347 57480.304584 0.000278 0.16697 0.01316 0.97917 0 29.44073 0.86466 24.95349 0.73277 4.91569 0.35942 4.16589 0.30447 57480.305174 0.000312 0.16089 0.01238 0.98148 0 27.52106 0.78748 23.43517 0.67057 4.42786 0.31643 3.76453 0.26904 57480.305753 0.000266 0.17630 0.01380 1.00000 0 28.64624 0.87248 24.36145 0.74198 5.05021 0.36426 4.29590 0.30984 57480.306467 0.000448 0.15765 0.00999 0.99355 0 28.30486 0.66296 24.19704 0.56674 4.46232 0.26285 3.81521 0.22474
