/* ** ** 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 57922.442483 0.000350 0.20651 0.01621 0.98347 0 18.06972 0.58199 16.14494 0.51996 3.73155 0.26712 3.33547 0.23877 57922.443220 0.000388 0.18382 0.01448 1.00000 0 17.88755 0.55284 15.96486 0.49342 3.28809 0.23830 2.93413 0.21266 57922.443993 0.000385 0.17744 0.01366 0.97744 0 19.32479 0.57614 17.31710 0.51628 3.42904 0.24346 3.07245 0.21815 57922.444777 0.000399 0.16546 0.01269 0.99275 0 20.02016 0.57755 17.76528 0.51244 3.31249 0.23538 2.94110 0.20894 57922.445500 0.000324 0.21464 0.01694 0.99107 0 18.87276 0.62595 16.66328 0.55259 4.05078 0.29003 3.57586 0.25598 57922.446183 0.000359 0.19425 0.01525 0.98387 0 18.62499 0.58713 16.69699 0.52635 3.61792 0.26006 3.24321 0.23313 57922.446924 0.000382 0.17929 0.01409 0.98485 0 18.98880 0.57461 17.01931 0.51501 3.40451 0.24684 3.05143 0.22124 57922.447714 0.000408 0.16880 0.01307 1.00000 0 18.60747 0.54787 16.67804 0.49106 3.14085 0.22484 2.81504 0.20152 57922.448527 0.000405 0.18235 0.01422 0.96429 0 18.02270 0.54579 16.07590 0.48677 3.28647 0.23625 2.93090 0.21068 57922.449300 0.000367 0.18388 0.01426 0.98425 0 19.32898 0.58884 17.32280 0.52772 3.55414 0.25338 3.18535 0.22709 57922.450020 0.000353 0.20058 0.01586 0.99180 0 18.14774 0.58520 16.25073 0.52403 3.64016 0.26274 3.25969 0.23528 57922.450775 0.000402 0.17504 0.01374 0.98561 0 18.37598 0.55526 16.38677 0.49511 3.21650 0.23312 2.86988 0.20800 57922.451539 0.000362 0.18410 0.01445 0.99200 0 19.47482 0.60014 17.27110 0.53222 3.58524 0.25881 3.18083 0.22959 57922.452271 0.000370 0.18426 0.01450 0.99219 0 18.88374 0.58203 16.91844 0.52145 3.47956 0.25191 3.11757 0.22570 57922.453050 0.000408 0.19393 0.01405 0.99291 0 18.78218 0.55131 16.82299 0.49380 3.64244 0.24123 3.26257 0.21607
