/* ** ** 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 54948.878704 0.000281 0.17546 0.01391 1.00000 0 25.07656 0.75671 23.00293 0.69411 4.39991 0.32255 4.03412 0.29572 54948.879279 0.000295 0.17428 0.01361 1.00000 0 24.00526 0.72148 22.21922 0.66780 4.18367 0.30159 3.87242 0.27915 54948.879855 0.000281 0.19579 0.01528 0.98969 0 23.14425 0.73132 21.29917 0.67299 4.53134 0.32345 4.17097 0.29770 54948.880431 0.000295 0.18593 0.01458 0.99020 0 23.20638 0.70962 21.35727 0.65305 4.31472 0.31152 3.96776 0.28642 54948.881030 0.000304 0.17576 0.01355 0.97143 0 24.08891 0.71275 22.30222 0.65988 4.23394 0.30151 3.91990 0.27915 54948.881600 0.000266 0.19564 0.01527 0.98913 0 24.13607 0.76073 22.34572 0.70430 4.72199 0.33712 4.37172 0.31212 54948.882161 0.000295 0.18058 0.01427 1.00000 0 23.17657 0.71275 21.32991 0.65592 4.18529 0.30465 3.84458 0.27984 54948.882757 0.000295 0.17550 0.01370 1.00000 0 23.83253 0.71295 22.06527 0.66008 4.18256 0.30151 3.87242 0.27915 54948.883353 0.000301 0.17712 0.01388 1.00000 0 23.19508 0.70341 21.47412 0.65122 4.10839 0.29682 3.80356 0.27480 54948.883932 0.000278 0.19264 0.01501 1.00000 0 23.68428 0.73992 21.78443 0.68055 4.56254 0.32562 4.19792 0.29952 54948.884525 0.000315 0.17014 0.01303 1.00000 0 23.48602 0.68986 21.74365 0.63868 3.99601 0.28250 3.69957 0.26154 54948.885116 0.000275 0.19147 0.01503 1.00000 0 23.57778 0.74285 21.82518 0.68764 4.51446 0.32459 4.17884 0.30046 54948.885674 0.000284 0.17373 0.01345 1.00000 0 25.23810 0.75634 23.36605 0.70023 4.38469 0.31304 4.05946 0.28982 54948.886244 0.000286 0.18308 0.01410 1.00000 0 24.03158 0.73450 22.24861 0.68000 4.39969 0.31104 4.07327 0.28796 54948.887025 0.000495 0.20201 0.01174 0.99423 0 22.65546 0.54334 20.97501 0.50304 4.57659 0.24216 4.23712 0.22420 54948.948669 0.000370 0.13649 0.01048 0.98438 0 24.74683 0.65319 22.96526 0.60616 3.37773 0.24353 3.13450 0.22600 54948.949340 0.000301 0.17422 0.01351 1.00000 0 23.70494 0.70961 21.98680 0.65817 4.12991 0.29556 3.83058 0.27413 54948.949953 0.000312 0.17290 0.01355 0.99074 0 23.12173 0.69259 21.27191 0.63717 3.99783 0.28962 3.67774 0.26646 54948.950564 0.000298 0.17987 0.01409 1.00000 0 23.06576 0.70479 21.34379 0.65218 4.14891 0.29914 3.83444 0.27646 54948.951183 0.000321 0.16302 0.01275 1.00000 0 23.47647 0.68234 21.77921 0.63301 3.82704 0.27790 3.55037 0.25781 54948.951802 0.000298 0.17785 0.01388 1.00000 0 23.36053 0.70912 21.66928 0.65778 4.15468 0.29877 3.85389 0.27714 54948.952398 0.000298 0.17739 0.01373 1.00000 0 23.58911 0.71365 21.88256 0.66203 4.18437 0.29801 3.88166 0.27645 54948.953021 0.000324 0.15680 0.01211 0.99107 0 24.74512 0.69718 22.95465 0.64674 3.88011 0.27894 3.59935 0.25875 54948.953631 0.000286 0.18312 0.01438 1.00000 0 23.51899 0.72320 21.81775 0.67089 4.30671 0.31122 3.99516 0.28870 54948.954259 0.000341 0.16105 0.01266 0.98305 0 22.54152 0.64985 20.91163 0.60286 3.63023 0.26561 3.36774 0.24640 54948.954890 0.000289 0.18571 0.01489 0.98000 0 22.96996 0.71359 21.30835 0.66197 4.26572 0.31519 3.95713 0.29239 54948.955466 0.000286 0.18095 0.01408 1.00000 0 23.97297 0.73091 22.23829 0.67802 4.33793 0.31044 4.02405 0.28798 54948.956059 0.000307 0.17290 0.01333 0.99057 0 23.89415 0.70838 22.16500 0.65711 4.13123 0.29415 3.83226 0.27286 54948.956640 0.000275 0.21250 0.01669 0.98947 0 21.74727 0.71412 20.17359 0.66244 4.62122 0.32978 4.28682 0.30591
