/* ** ** 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 55357.925923 0.000399 0.14206 0.01843 0.99275 0 7.77198 0.35788 7.00370 0.32249 1.10408 0.13390 0.99436 0.12058 55357.926733 0.000411 0.09844 0.01476 0.97887 0 8.10325 0.36089 7.23819 0.32237 0.79770 0.11424 0.71330 0.10217 55357.927503 0.000359 0.11175 0.01707 0.96774 0 8.16655 0.38779 7.33622 0.34830 0.91260 0.13249 0.81776 0.11866 55357.928379 0.000518 0.12922 0.01464 0.98883 0 8.48040 0.32548 7.70873 0.29586 1.09581 0.11681 0.99601 0.10617 55357.930084 0.001186 0.15066 0.01104 0.99208 0 7.92889 0.20856 7.20577 0.18954 1.19458 0.08171 1.08565 0.07426 55357.992442 0.000359 0.10801 0.01630 0.97581 0 8.43180 0.39667 7.56926 0.35611 0.91068 0.13062 0.81873 0.11742 55357.993145 0.000344 0.10977 0.01636 0.98319 0 8.60156 0.40478 7.79357 0.36677 0.94422 0.13354 0.85613 0.12107 55357.994077 0.000587 0.13637 0.01455 0.99015 0 8.07445 0.30079 7.30484 0.27210 1.10108 0.11011 0.99668 0.09967 55357.995454 0.000790 0.12657 0.01169 0.99267 0 8.80136 0.27265 7.82861 0.24249 1.11395 0.09689 0.98985 0.08608 55357.996571 0.000327 0.11140 0.01683 0.97345 0 9.08608 0.43081 8.07781 0.38297 1.01222 0.14517 0.90060 0.12917 55357.997699 0.000802 0.13167 0.01214 0.98556 0 8.41883 0.26506 7.51554 0.23661 1.10848 0.09604 0.98993 0.08577 55357.999250 0.000749 0.13421 0.01277 0.98456 0 8.30899 0.27142 7.43659 0.24291 1.11515 0.09966 0.99696 0.08909
