/* ** ** 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 58176.305227 0.000243 0.21712 0.01714 1.00000 0 24.53532 0.81598 22.01192 0.73204 5.32722 0.38134 4.77610 0.34188 58176.305757 0.000286 0.17746 0.01407 1.00000 0 24.65098 0.75490 22.28657 0.68249 4.37451 0.31983 3.95481 0.28914 58176.306298 0.000255 0.21379 0.01705 0.98864 0 23.58841 0.78767 21.23792 0.70917 5.04296 0.36531 4.54434 0.32916 58176.306833 0.000281 0.18407 0.01481 0.98969 0 24.43636 0.76569 21.92528 0.68701 4.49790 0.33332 4.04031 0.29939 58176.307377 0.000263 0.18923 0.01516 1.00000 0 25.52409 0.80858 22.63878 0.71715 4.82996 0.35545 4.28239 0.31520 58176.307898 0.000258 0.20196 0.01580 1.00000 0 24.66721 0.80047 22.20313 0.72043 4.98177 0.35464 4.48134 0.31899 58176.308410 0.000255 0.20351 0.01618 1.00000 0 24.83038 0.80779 22.19699 0.72202 5.05331 0.36656 4.51746 0.32766 58176.308948 0.000284 0.17138 0.01343 1.00000 0 26.27873 0.78512 23.56602 0.70402 4.50357 0.32621 4.03426 0.29221 58176.309487 0.000255 0.19227 0.01530 1.00000 0 25.67473 0.81944 23.26831 0.74265 4.93647 0.35995 4.47193 0.32608 58176.310004 0.000263 0.18263 0.01422 1.00000 0 26.48953 0.81764 24.00633 0.74099 4.83785 0.34579 4.38477 0.31340 58176.310525 0.000258 0.20915 0.01644 1.00000 0 24.01143 0.79531 21.55489 0.71393 5.02193 0.35808 4.50581 0.32123 58176.311049 0.000266 0.19218 0.01500 0.97826 0 25.89473 0.81155 23.08401 0.72347 4.97653 0.35565 4.43349 0.31688 58176.311570 0.000255 0.19300 0.01535 1.00000 0 25.74257 0.81870 23.16211 0.73662 4.96832 0.36230 4.47193 0.32608 58176.312059 0.000234 0.20521 0.01665 1.00000 0 25.75346 0.85150 23.33571 0.77156 5.28480 0.39161 4.78852 0.35483 58176.312533 0.000240 0.22377 0.01794 1.00000 0 23.49371 0.80778 21.28694 0.73191 5.25711 0.38079 4.76334 0.34502 58176.313028 0.000255 0.19668 0.01546 0.98864 0 25.85419 0.82248 23.45453 0.74615 5.08512 0.36547 4.61342 0.33156 58176.313561 0.000278 0.17857 0.01411 0.98958 0 25.61436 0.77960 23.19755 0.70604 4.57400 0.33352 4.14242 0.30205 58176.314107 0.000269 0.18287 0.01427 1.00000 0 25.75509 0.79425 23.34428 0.71990 4.70975 0.33749 4.26893 0.30590 58176.314634 0.000258 0.18845 0.01493 0.98876 0 26.46634 0.82619 23.98081 0.74860 4.98769 0.36321 4.51945 0.32911 58176.315155 0.000263 0.20148 0.01598 0.98901 0 24.20757 0.77817 21.92259 0.70472 4.87732 0.35377 4.41707 0.32038 58176.315664 0.000246 0.20877 0.01621 0.98824 0 25.35442 0.82376 22.96172 0.74603 5.29315 0.37335 4.79370 0.33812 58176.316182 0.000272 0.18043 0.01411 1.00000 0 25.84572 0.79201 23.41827 0.71763 4.66338 0.33554 4.22538 0.30402 58176.316908 0.000454 0.19313 0.01150 1.00000 0 25.27381 0.60496 22.89611 0.54805 4.88102 0.26614 4.42169 0.24109
