/* ** ** 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 54945.001754 0.000286 0.17435 0.01352 0.97980 0 25.14173 0.74291 23.44987 0.69292 4.38341 0.31423 4.08844 0.29309 54945.002330 0.000289 0.16055 0.01261 1.00000 0 26.11892 0.75598 24.36130 0.70511 4.19347 0.30620 3.91128 0.28560 54945.002923 0.000304 0.15439 0.01201 0.99048 0 26.34190 0.74220 24.56928 0.69225 4.06688 0.29482 3.79321 0.27498 54945.003548 0.000321 0.14554 0.01103 1.00000 0 26.59135 0.72419 24.80194 0.67546 3.87003 0.27365 3.60961 0.25524 54945.004144 0.000275 0.16633 0.01288 1.00000 0 26.90775 0.78601 25.09705 0.73312 4.47569 0.32085 4.17451 0.29926 54945.004705 0.000286 0.17436 0.01360 0.98990 0 24.79773 0.74352 23.12902 0.69349 4.32377 0.31138 4.03281 0.29043 54945.005249 0.000258 0.19848 0.01551 0.98876 0 24.42705 0.77873 22.78329 0.72633 4.84832 0.34597 4.52206 0.32269 54945.005787 0.000281 0.16975 0.01326 0.98969 0 25.91310 0.76517 24.16933 0.71368 4.39863 0.31824 4.10264 0.29682 54945.006372 0.000304 0.15758 0.01206 1.00000 0 25.87350 0.73598 24.13240 0.68645 4.07727 0.28962 3.80289 0.27013 54945.006942 0.000266 0.17314 0.01339 1.00000 0 26.78552 0.79991 24.98305 0.74608 4.63752 0.33093 4.32545 0.30866 54945.007489 0.000281 0.17167 0.01321 1.00000 0 26.09118 0.76889 24.33543 0.71715 4.47906 0.31847 4.17765 0.29704 54945.008062 0.000292 0.16225 0.01256 0.99010 0 26.24859 0.75750 24.48225 0.70652 4.25878 0.30591 3.97219 0.28533 54945.008646 0.000292 0.16916 0.01324 1.00000 0 24.75632 0.73101 23.09040 0.68181 4.18768 0.30357 3.90588 0.28314 54945.009202 0.000263 0.17834 0.01396 1.00000 0 26.15240 0.79495 24.39253 0.74145 4.66392 0.33655 4.35007 0.31390 54945.009749 0.000284 0.17453 0.01346 0.97959 0 25.59279 0.75836 23.87058 0.70733 4.46666 0.31793 4.16609 0.29654 54945.010298 0.000266 0.18406 0.01430 1.00000 0 25.40337 0.77598 23.69391 0.72376 4.67580 0.33415 4.36115 0.31166 54945.010851 0.000286 0.16669 0.01288 1.00000 0 25.89536 0.75736 24.15279 0.70639 4.31655 0.30865 4.02608 0.28788 54945.011485 0.000347 0.17594 0.01241 0.99085 0 24.97397 0.67471 23.29340 0.62931 4.39389 0.28633 4.09821 0.26706 54945.051677 0.000284 0.15814 0.01221 1.00000 0 28.02410 0.80093 25.57943 0.73106 4.43180 0.31790 4.04519 0.29017 54945.052256 0.000295 0.16456 0.01268 1.00000 0 25.96700 0.75496 23.70178 0.68910 4.27317 0.30506 3.90041 0.27845 54945.052832 0.000281 0.16824 0.01298 1.00000 0 26.88243 0.78916 24.53735 0.72031 4.52274 0.32277 4.12820 0.29461 54945.053361 0.000249 0.18708 0.01460 1.00000 0 27.13071 0.84461 24.76398 0.77093 5.07571 0.36316 4.63293 0.33148 54945.053893 0.000284 0.17118 0.01325 0.98980 0 26.28852 0.77642 23.99525 0.70869 4.50011 0.32198 4.10755 0.29389 54945.054426 0.000249 0.18934 0.01485 1.00000 0 26.71294 0.83629 24.38265 0.76333 5.05771 0.36361 4.61651 0.33189 54945.055115 0.000440 0.16453 0.01001 0.97368 0 28.30164 0.64414 25.83276 0.58795 4.65652 0.26278 4.25031 0.23986
