/* ** ** 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 57416.421430 0.000367 0.15593 0.01210 1.00000 0 34.11372 0.98461 19.93896 0.57053 5.31941 0.38309 3.12585 0.22402 57416.422217 0.000420 0.16755 0.01297 1.00000 0 35.10623 1.04081 16.47322 0.48791 5.88216 0.42075 2.75163 0.19670 57416.423045 0.000408 0.15641 0.01204 0.99291 0 37.27517 1.06106 18.19850 0.51804 5.83024 0.41685 2.84991 0.20372 57416.423864 0.000405 0.15977 0.01257 0.99286 0 36.07984 1.04666 17.61527 0.51098 5.76446 0.42170 2.81625 0.20597 57416.424688 0.000420 0.15457 0.01215 0.99310 0 36.89773 1.05575 17.55499 0.50208 5.70328 0.41738 2.71846 0.19881 57416.425574 0.000466 0.14411 0.01121 0.98137 0 36.46163 0.99482 17.46173 0.47346 5.25458 0.38274 2.48924 0.18082 57416.426488 0.000448 0.15149 0.01198 0.99355 0 36.20887 1.03161 16.70859 0.47572 5.48517 0.40461 2.52998 0.18629 57416.427431 0.000495 0.13166 0.01017 0.98246 0 37.66388 0.98394 17.83082 0.46529 4.95883 0.36039 2.34107 0.17006 57416.428354 0.000428 0.15830 0.01229 0.97297 0 35.62632 1.01888 17.35433 0.49632 5.63954 0.40696 2.74404 0.19799 57416.429185 0.000402 0.16290 0.01276 0.99281 0 37.01096 1.07802 17.52614 0.51027 6.02905 0.43826 2.85000 0.20703 57416.430004 0.000417 0.15140 0.01210 1.00000 0 37.40557 1.06682 17.74441 0.50548 5.66316 0.42275 2.68009 0.20004 57416.430860 0.000440 0.15730 0.01246 0.99342 0 34.27806 0.99300 16.48333 0.47750 5.39177 0.39749 2.59458 0.19130 57416.431966 0.000666 0.16040 0.00999 0.99130 0 35.20196 0.80535 17.08465 0.39077 5.64644 0.32702 2.73829 0.15859
