/* ** ** 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 58526.047797 0.000362 0.16410 0.01267 0.98400 0 25.37119 0.73353 19.71543 0.56992 4.16329 0.29801 3.23630 0.23167 58526.048540 0.000382 0.15561 0.01196 0.99242 0 24.67042 0.69671 19.50130 0.55073 3.83904 0.27451 3.03216 0.21681 58526.049324 0.000402 0.15228 0.01165 0.99281 0 23.81886 0.66488 18.95378 0.52907 3.62715 0.25839 2.88670 0.20564 58526.050065 0.000339 0.16575 0.01284 1.00000 0 25.71094 0.75138 20.42244 0.59683 4.26171 0.30586 3.38515 0.24295 58526.050757 0.000353 0.16832 0.01316 1.00000 0 24.15977 0.71411 19.21639 0.56800 4.06650 0.29436 3.23452 0.23414 58526.051463 0.000353 0.16821 0.01301 0.97541 0 25.09116 0.72940 19.93042 0.57938 4.22059 0.30247 3.35225 0.24024 58526.052203 0.000388 0.14517 0.01134 0.99254 0 25.46733 0.70061 20.21706 0.55618 3.69716 0.27035 2.93463 0.21460 58526.052982 0.000391 0.15230 0.01193 0.97778 0 24.44018 0.68573 19.41457 0.54473 3.72224 0.27219 2.95686 0.21622 58526.053728 0.000356 0.16935 0.01316 1.00000 0 24.11326 0.71489 19.06549 0.56517 4.08370 0.29339 3.22694 0.23186 58526.054408 0.000324 0.18713 0.01464 0.99107 0 24.01540 0.74308 19.10939 0.59127 4.49399 0.32290 3.57580 0.25692 58526.055161 0.000428 0.14363 0.01105 1.00000 0 23.53579 0.64103 18.71019 0.50960 3.38056 0.24317 2.68761 0.19332 58526.055991 0.000402 0.14790 0.01131 1.00000 0 24.42476 0.67394 19.41615 0.53574 3.61247 0.25764 2.87206 0.20484 58526.056766 0.000373 0.14850 0.01145 0.98450 0 26.38741 0.72651 20.94005 0.57653 3.91843 0.28227 3.10953 0.22400 58526.057493 0.000353 0.16568 0.01280 0.98361 0 25.20936 0.73085 20.02272 0.58049 4.17669 0.29899 3.31721 0.23746 58526.058422 0.000576 0.17175 0.01048 0.99497 0 23.67640 0.55338 18.80085 0.43943 4.06639 0.22923 3.22888 0.18202
