/* ** ** 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 54954.957343 0.000521 0.14799 0.01152 0.96111 0 17.58221 0.48066 15.25724 0.41709 2.60191 0.18970 2.26161 0.16489 54954.958367 0.000503 0.14298 0.01139 0.96552 0 18.65145 0.50654 15.95616 0.43332 2.66678 0.19971 2.27991 0.17081 54954.959293 0.000422 0.17678 0.01435 0.97260 0 17.82920 0.54537 15.20397 0.46506 3.15189 0.23706 2.68908 0.20225 54954.960213 0.000498 0.15010 0.01175 0.96512 0 18.37014 0.51017 15.65491 0.43475 2.75737 0.20183 2.34989 0.17199 54954.961179 0.000469 0.16372 0.01280 0.96296 0 18.12942 0.52117 15.39691 0.44262 2.96816 0.21583 2.52091 0.18331 54954.962157 0.000509 0.14782 0.01132 0.97727 0 18.43752 0.50164 15.65386 0.42591 2.72535 0.19517 2.31376 0.16569 54954.963213 0.000547 0.13844 0.01051 0.97354 0 18.40950 0.48406 15.63771 0.41118 2.54853 0.18158 2.16475 0.15424 54954.964290 0.000530 0.13855 0.01064 0.97814 0 18.67525 0.49493 15.91562 0.42178 2.58742 0.18648 2.20551 0.15896 54954.965329 0.000509 0.14737 0.01129 0.98864 0 18.13667 0.49514 15.50903 0.42338 2.67278 0.19139 2.28716 0.16379 54954.966391 0.000553 0.13146 0.01013 0.97906 0 18.60764 0.48074 15.96363 0.41241 2.44612 0.17766 2.09858 0.15242 54954.967490 0.000547 0.14632 0.01117 0.98413 0 17.84234 0.47628 15.16004 0.40468 2.61077 0.18679 2.21826 0.15871
