/* ** ** 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 57082.211784 0.000382 0.18090 0.01409 0.99242 0 18.52064 0.56540 16.75632 0.51154 3.35045 0.23999 3.03128 0.21713 57082.212545 0.000379 0.18134 0.01395 0.99237 0 18.78506 0.56910 16.99555 0.51488 3.40656 0.24088 3.08204 0.21793 57082.213355 0.000431 0.15558 0.01234 0.99329 0 18.63307 0.53261 16.85804 0.48187 2.89899 0.21450 2.62282 0.19407 57082.214154 0.000367 0.18988 0.01490 0.97638 0 18.55738 0.57515 16.78956 0.52036 3.52369 0.25403 3.18801 0.22983 57082.214906 0.000385 0.17825 0.01407 0.99248 0 18.49652 0.56336 16.73450 0.50970 3.29703 0.24016 2.98295 0.21728 57082.215659 0.000367 0.18297 0.01426 0.99213 0 19.03763 0.58378 17.22406 0.52817 3.48340 0.24951 3.15157 0.22574 57082.216700 0.000674 0.18268 0.01080 0.98793 0 18.07829 0.42036 16.35611 0.38032 3.30262 0.17955 2.98800 0.16244 57082.233801 0.000576 0.17632 0.01430 0.96482 0 19.96999 0.61571 11.35648 0.35014 3.52104 0.26416 2.00234 0.15022 57082.234993 0.000616 0.17192 0.01351 0.98592 0 19.16458 0.57795 10.89846 0.32867 3.29468 0.23915 1.87361 0.13600 57082.236558 0.000949 0.18252 0.01121 0.99085 0 19.21780 0.46524 10.92873 0.26457 3.50764 0.19805 1.99472 0.11263
