/* ** ** 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 56653.145716 0.000469 0.14228 0.01089 0.98765 0 19.75532 0.53133 17.44715 0.46918 2.81082 0.20135 2.48188 0.17777 56653.146628 0.000443 0.15167 0.01168 0.99346 0 19.47545 0.54657 17.33246 0.48644 2.95381 0.21185 2.62713 0.18842 56653.147510 0.000440 0.16345 0.01268 0.98684 0 18.12294 0.52636 16.18994 0.47012 2.96223 0.21306 2.64880 0.19046 56653.148393 0.000443 0.14402 0.01120 1.00000 0 19.96421 0.54559 17.88778 0.48885 2.87532 0.20941 2.57355 0.18746 56653.149307 0.000472 0.14193 0.01100 0.99387 0 19.13458 0.52109 17.12005 0.46623 2.71585 0.19704 2.42922 0.17627 56653.150224 0.000446 0.15659 0.01227 0.98052 0 18.71469 0.52979 16.66365 0.47172 2.93052 0.21419 2.60910 0.19077 56653.151095 0.000425 0.15758 0.01222 1.00000 0 19.09322 0.54566 17.07387 0.48793 3.00868 0.21691 2.68923 0.19387 56653.151952 0.000431 0.16049 0.01252 1.00000 0 18.42240 0.53640 16.53908 0.48155 2.95655 0.21396 2.65461 0.19212 56653.152800 0.000417 0.16267 0.01255 0.97222 0 19.57791 0.55996 17.44915 0.49907 3.18477 0.22810 2.83643 0.20317 56653.153633 0.000417 0.15675 0.01215 0.99306 0 19.90795 0.56689 17.64836 0.50252 3.12053 0.22500 2.76445 0.19930 56653.154510 0.000460 0.15469 0.01206 0.99371 0 18.05531 0.51365 16.10663 0.45815 2.79291 0.20268 2.49072 0.18073 56653.155375 0.000405 0.16724 0.01302 0.98571 0 19.30892 0.56843 17.12643 0.50416 3.22924 0.23275 2.86462 0.20652 56653.156353 0.000573 0.16317 0.01062 0.98990 0 19.48635 0.47578 17.41280 0.42512 3.17965 0.19177 2.84371 0.17152
