/* ** ** 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 55953.465824 0.000431 0.10269 0.01586 0.96644 0 10.07046 0.46741 6.56920 0.30129 1.03413 0.15230 0.68129 0.09889 55953.466707 0.000451 0.09395 0.01392 0.98077 0 9.58852 0.41914 6.93759 0.30290 0.90083 0.12750 0.65468 0.09259 55953.467543 0.000385 0.11102 0.01657 0.99248 0 9.23139 0.43913 6.83472 0.32512 1.02490 0.14494 0.75884 0.10732 55953.468237 0.000310 0.13477 0.02108 0.99065 0 9.21730 0.48987 6.79241 0.36100 1.24217 0.18271 0.91580 0.13470 55953.468952 0.000405 0.10632 0.01601 0.97857 0 9.21645 0.42789 6.80760 0.31606 0.97992 0.14040 0.72362 0.10367 55953.469678 0.000321 0.11560 0.01728 0.98198 0 10.78180 0.52230 7.95501 0.38535 1.24639 0.17627 0.91896 0.12996 55953.470376 0.000376 0.09973 0.01497 0.96923 0 10.65625 0.47648 7.88685 0.35265 1.06278 0.15227 0.78679 0.11272 55953.471290 0.000538 0.07326 0.01100 0.96774 0 10.05564 0.38770 7.45026 0.28723 0.73671 0.10693 0.54503 0.07911 55953.472190 0.000362 0.10708 0.01614 0.99200 0 10.09367 0.47202 7.46264 0.34898 1.08080 0.15483 0.79948 0.11454 55953.472974 0.000422 0.09585 0.01404 0.95890 0 10.32739 0.44538 7.60747 0.32809 0.98990 0.13862 0.72979 0.10219 55953.473726 0.000330 0.12600 0.01941 1.00000 0 9.21904 0.47560 6.83073 0.35239 1.16162 0.16860 0.86057 0.12492 55953.474404 0.000347 0.10607 0.01599 0.98333 0 10.63593 0.49791 7.89977 0.36979 1.12811 0.16164 0.84014 0.12037 55953.475185 0.000434 0.09796 0.01489 0.98000 0 9.20984 0.41526 6.81246 0.30717 0.90216 0.13097 0.66738 0.09687 55953.475969 0.000350 0.10573 0.01632 0.97521 0 10.55781 0.49421 7.78482 0.36440 1.11626 0.16417 0.82267 0.12100 55953.476710 0.000391 0.11116 0.01641 0.97037 0 9.45030 0.44238 7.01546 0.32840 1.05049 0.14710 0.77992 0.10921 55953.477783 0.000683 0.10430 0.01177 0.99153 0 9.66136 0.33613 7.17958 0.24979 1.00771 0.10821 0.74899 0.08043
