/* ** ** 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 59188.744070 0.000281 0.20206 0.01590 1.00000 0 22.89578 0.74507 20.23638 0.65847 4.62625 0.33156 4.09288 0.29329 59188.744657 0.000307 0.18453 0.01454 0.99057 0 22.90401 0.71044 20.38597 0.63226 4.22642 0.30613 3.76529 0.27273 59188.745253 0.000289 0.18892 0.01479 1.00000 0 23.55605 0.73749 21.13053 0.66151 4.45023 0.31935 3.99187 0.28648 59188.745829 0.000286 0.20267 0.01595 0.98990 0 22.13782 0.72110 19.98900 0.65111 4.48662 0.32151 4.05112 0.29030 59188.746399 0.000284 0.19572 0.01542 1.00000 0 22.93050 0.73605 20.70780 0.66470 4.48796 0.32292 4.05290 0.29161 59188.746963 0.000281 0.20540 0.01638 0.98969 0 22.33850 0.73066 20.03976 0.65544 4.58844 0.33376 4.12011 0.29963 59188.747513 0.000269 0.21298 0.01691 0.98925 0 22.44437 0.74393 20.15930 0.66815 4.78016 0.34481 4.29544 0.30987 59188.748060 0.000278 0.21570 0.01706 1.00000 0 21.63137 0.72717 19.37422 0.65122 4.66584 0.33394 4.17907 0.29915 59188.748604 0.000266 0.21240 0.01707 0.98913 0 22.43594 0.74870 20.25643 0.67597 4.76539 0.34841 4.30246 0.31456 59188.749174 0.000304 0.19288 0.01507 0.97143 0 22.78203 0.71728 20.24870 0.63737 4.39427 0.31413 3.91189 0.27960 59188.749770 0.000292 0.18880 0.01462 1.00000 0 23.57906 0.73308 21.24151 0.66034 4.45181 0.31578 4.01013 0.28446 59188.750332 0.000269 0.19116 0.01524 1.00000 0 24.58269 0.78065 22.03768 0.69987 4.69935 0.34360 4.20993 0.30780 59188.750884 0.000284 0.20664 0.01640 1.00000 0 21.73334 0.71284 19.62124 0.64356 4.49101 0.32445 4.05468 0.29292 59188.751483 0.000315 0.17992 0.01436 1.00000 0 22.00719 0.68002 19.87049 0.61400 3.95960 0.29144 3.57518 0.26315 59188.752276 0.000477 0.19589 0.01194 0.99601 0 22.78299 0.56343 20.49615 0.50687 4.46297 0.24853 4.01478 0.22356
