/* ** ** 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 55682.005002 0.000437 0.14271 0.02154 0.95364 0 5.41856 0.28610 4.87216 0.25727 0.77328 0.10937 0.69560 0.09837 55682.005963 0.000524 0.07465 0.01308 0.97238 0 5.90573 0.27273 5.33580 0.24641 0.44084 0.07452 0.39839 0.06734 55682.006999 0.000512 0.10834 0.01698 0.98305 0 5.61373 0.26906 5.09089 0.24400 0.60817 0.09075 0.55154 0.08230 55682.008174 0.000663 0.07667 0.01169 0.98690 0 6.17326 0.24623 5.59911 0.22333 0.47329 0.06967 0.42928 0.06319 55682.009392 0.000556 0.10044 0.01509 0.96354 0 5.90348 0.26586 5.33368 0.24021 0.59293 0.08499 0.53577 0.07678 55682.010494 0.000547 0.09946 0.01494 0.97884 0 5.94005 0.26658 5.38659 0.24174 0.59082 0.08467 0.53577 0.07678 55682.011686 0.000645 0.08160 0.01265 0.97309 0 5.98359 0.24935 5.41101 0.22547 0.48828 0.07289 0.44225 0.06599 55682.012902 0.000570 0.09934 0.01473 0.96954 0 5.82024 0.26002 5.27876 0.23584 0.57820 0.08177 0.52443 0.07417 55682.013770 0.000298 0.07065 0.01635 0.98058 0 6.19202 0.36824 5.61531 0.33395 0.43744 0.09781 0.39670 0.08870 55682.014415 0.000347 0.07841 0.01698 0.96667 0 5.58615 0.32555 5.06572 0.29522 0.43802 0.09133 0.39721 0.08282 55682.015361 0.000599 0.10295 0.01507 0.99517 0 5.51424 0.24567 5.00178 0.22284 0.56767 0.07918 0.51495 0.07183
