/* ** ** 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 55240.003458 0.000421 0.22366 0.03003 0.99892 1 22.39328 1.30445 4.27353 0.24894 5.00839 0.60584 0.95590 0.11563 55240.004914 0.000243 0.18201 0.01423 1.00000 0 29.26656 0.89725 25.98043 0.79651 5.32683 0.38324 4.72864 0.34020 55240.005409 0.000252 0.18611 0.01463 0.98851 0 27.71100 0.86646 24.69220 0.77196 5.15735 0.37204 4.59538 0.33147 55240.005912 0.000252 0.18797 0.01465 0.98851 0 27.87638 0.85947 24.82566 0.76540 5.23992 0.37509 4.66526 0.33392 55240.006407 0.000243 0.18268 0.01425 1.00000 0 29.14489 0.89737 25.87217 0.79660 5.32433 0.38151 4.72648 0.33867 55240.006925 0.000275 0.15794 0.01214 0.98947 0 29.68504 0.84061 26.86869 0.76088 4.68837 0.33504 4.24497 0.30339 55240.007423 0.000223 0.19781 0.01543 0.98701 0 29.61779 0.94542 26.49861 0.84580 5.85863 0.41698 5.24797 0.37355 55240.007918 0.000272 0.16211 0.01259 1.00000 0 29.49536 0.85528 26.20389 0.75984 4.78140 0.34447 4.24884 0.30611 55240.008430 0.000240 0.19094 0.01528 1.00000 0 27.62969 0.87733 24.85507 0.78916 5.27562 0.38753 4.74610 0.34876 55240.008948 0.000278 0.15510 0.01194 1.00000 0 29.95464 0.85403 26.76219 0.76296 4.64582 0.33210 4.15653 0.29707 55240.009474 0.000249 0.17065 0.01347 0.98837 0 30.20626 0.89675 27.02464 0.80230 5.15482 0.37687 4.60658 0.33674 55240.009966 0.000243 0.18598 0.01437 1.00000 0 28.46473 0.88786 25.65491 0.80029 5.29375 0.37434 4.76984 0.33728 55240.010481 0.000272 0.16172 0.01257 1.00000 0 28.92492 0.83781 25.97283 0.75228 4.67788 0.33747 4.20428 0.30326 55240.011005 0.000252 0.17504 0.01358 1.00000 0 29.28127 0.88243 26.23813 0.79078 5.12554 0.36632 4.58652 0.32780 55240.011506 0.000249 0.18257 0.01407 0.98837 0 29.05831 0.88490 25.97903 0.79107 5.30514 0.37567 4.73944 0.33566 55240.011980 0.000226 0.20152 0.01600 1.00000 0 28.08408 0.91439 25.16581 0.81927 5.65944 0.40996 5.06903 0.36711 55240.012478 0.000272 0.15736 0.01215 1.00000 0 30.13190 0.85846 26.94805 0.76769 4.74154 0.34032 4.24691 0.30476 55240.012978 0.000229 0.18927 0.01498 1.00000 0 29.01657 0.91447 26.29782 0.82878 5.49202 0.39872 4.97951 0.36158 55240.013438 0.000231 0.19223 0.01510 1.00000 0 28.32058 0.89198 25.82894 0.81344 5.44412 0.39167 4.96507 0.35721 55240.013890 0.000220 0.19559 0.01542 0.98684 0 29.85953 0.94971 26.95392 0.85722 5.84010 0.42143 5.26937 0.38009 55240.014347 0.000237 0.18107 0.01410 0.97561 0 30.61812 0.93257 27.41932 0.83502 5.54388 0.39732 4.96280 0.35560 55240.014937 0.000353 0.18044 0.01175 0.98361 0 29.92894 0.75064 26.97197 0.67639 5.40027 0.32445 4.87173 0.29272
