/* ** ** 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 59306.987241 0.000394 0.12507 0.00939 0.99265 0 25.77481 0.64747 23.72136 0.59588 3.22361 0.22795 2.96790 0.20986 59306.988042 0.000408 0.11947 0.00923 1.00000 0 25.42512 0.63751 23.25047 0.58293 3.03744 0.22203 2.77705 0.20300 59306.988849 0.000399 0.12752 0.00970 0.98551 0 24.80989 0.63478 22.88490 0.58550 3.16386 0.22673 2.91931 0.20918 59306.989651 0.000402 0.12019 0.00901 0.98561 0 26.47183 0.64978 24.46635 0.60055 3.18155 0.22532 2.94053 0.20825 59306.990455 0.000402 0.13184 0.01017 1.00000 0 23.59959 0.61510 21.81372 0.56855 3.11140 0.22593 2.87597 0.20883 59306.991292 0.000434 0.11362 0.00859 1.00000 0 25.20697 0.61101 23.29571 0.56468 2.86398 0.20521 2.64684 0.18965 59306.992154 0.000428 0.11452 0.00883 0.99324 0 25.16673 0.61503 23.25957 0.56842 2.88218 0.21068 2.66370 0.19471 59306.993033 0.000451 0.10446 0.00814 0.98718 0 26.10247 0.60893 24.12468 0.56279 2.72674 0.20280 2.52016 0.18744 59306.993901 0.000417 0.12167 0.00938 0.99306 0 24.47145 0.61487 22.62005 0.56835 2.97744 0.21707 2.75222 0.20065 59306.994749 0.000431 0.11741 0.00906 0.98658 0 24.54411 0.60661 22.68773 0.56073 2.88163 0.21064 2.66370 0.19471 59306.995626 0.000446 0.11264 0.00844 0.99351 0 25.16419 0.60114 23.25802 0.55561 2.83461 0.20126 2.61993 0.18602 59306.996477 0.000405 0.12640 0.00968 1.00000 0 24.16400 0.61967 22.33286 0.57271 3.05437 0.22031 2.82289 0.20362 59306.997385 0.000503 0.11737 0.00817 0.98276 0 25.40820 0.57190 23.48420 0.52859 2.98216 0.19656 2.75633 0.18168
