/* ** ** 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 55672.152323 0.000573 0.13251 0.01010 0.99495 0 16.75982 0.43701 15.21311 0.39666 2.22084 0.15914 2.01521 0.14442 55672.153481 0.000584 0.13375 0.01014 0.99505 0 16.61797 0.43450 14.82241 0.38752 2.22272 0.15821 1.98424 0.14125 55672.154641 0.000576 0.13776 0.01058 0.98995 0 16.56512 0.43865 14.72576 0.38993 2.28204 0.16444 2.02708 0.14608 55672.155758 0.000541 0.14722 0.01121 1.00000 0 16.25686 0.44541 14.57269 0.39925 2.39339 0.16996 2.14350 0.15220 55672.156808 0.000509 0.15324 0.01172 0.98864 0 16.71760 0.46906 14.93542 0.41902 2.56182 0.18235 2.29213 0.16317 55672.157824 0.000506 0.15499 0.01201 0.99429 0 16.49144 0.46697 14.65952 0.41506 2.55602 0.18440 2.27103 0.16385 55672.158840 0.000509 0.14553 0.01123 0.99432 0 17.45537 0.47934 15.51638 0.42607 2.54026 0.18327 2.25806 0.16291 55672.159893 0.000544 0.14368 0.01108 0.99468 0 16.52440 0.45029 14.72332 0.40119 2.37414 0.17131 2.11316 0.15246 55672.160961 0.000524 0.15449 0.01202 0.99448 0 15.93703 0.45110 14.21725 0.40241 2.46208 0.17840 2.19626 0.15910 55672.162020 0.000535 0.14892 0.01128 0.98919 0 16.46994 0.45339 14.74957 0.40600 2.45269 0.17301 2.20039 0.15520 55672.163093 0.000538 0.14357 0.01128 0.99462 0 16.46502 0.45095 14.66230 0.40156 2.36390 0.17409 2.10623 0.15506 55672.164453 0.000822 0.13100 0.00860 0.99296 0 16.20980 0.36206 14.48354 0.32348 2.12351 0.13117 1.89856 0.11727
