/* ** ** 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 55576.480722 0.000509 0.11451 0.01315 0.99432 0 10.25048 0.37578 8.61351 0.31571 1.17379 0.12775 0.98411 0.10710 55576.481599 0.000367 0.09250 0.01383 0.96063 0 10.28627 0.43920 8.78311 0.37502 0.95152 0.13633 0.81255 0.11642 55576.482311 0.000344 0.09339 0.01380 0.95798 0 11.14607 0.47885 9.41447 0.40435 1.04089 0.14722 0.87866 0.12426 55576.483017 0.000362 0.08768 0.01294 0.99200 0 10.93011 0.46150 9.23734 0.39001 0.95836 0.13554 0.80780 0.11424 55576.483740 0.000362 0.10969 0.01480 0.98400 0 10.68599 0.45587 9.07523 0.38716 1.17219 0.15009 0.99352 0.12721 55576.484423 0.000321 0.10204 0.01554 1.00000 0 10.19661 0.46973 8.66712 0.39926 1.04046 0.15103 0.88374 0.12830 55576.485103 0.000359 0.09731 0.01464 0.99194 0 9.83636 0.43768 8.35260 0.37165 0.95718 0.13752 0.81381 0.11692 55576.485916 0.000454 0.10237 0.01248 1.00000 0 11.15322 0.41305 9.53138 0.35299 1.14178 0.13258 0.97549 0.11327 55576.486793 0.000422 0.07821 0.01149 0.98630 0 10.41449 0.41395 8.89428 0.35353 0.81454 0.11519 0.69560 0.09837 55576.487615 0.000399 0.08416 0.01239 0.97101 0 10.40253 0.42511 8.88066 0.36291 0.87551 0.12382 0.74751 0.10571 55576.488500 0.000486 0.06626 0.00958 0.97619 0 11.03142 0.39818 9.38300 0.33868 0.73098 0.10236 0.62299 0.08724 55576.489417 0.000431 0.11148 0.01406 0.95973 0 10.36257 0.40827 8.85635 0.34892 1.15524 0.13837 0.98742 0.11827 55576.490144 0.000295 0.10958 0.01635 1.00000 0 10.48920 0.49773 8.96204 0.42526 1.14939 0.16255 0.98203 0.13888 55576.490876 0.000437 0.08340 0.01216 0.97351 0 9.76143 0.39486 8.33668 0.33722 0.81409 0.11400 0.69503 0.09732 55576.491741 0.000428 0.07030 0.01069 0.99324 0 10.98929 0.42311 9.39218 0.36162 0.77257 0.11366 0.66027 0.09714 55576.492542 0.000373 0.08871 0.01313 0.97674 0 10.59121 0.44698 9.05014 0.38195 0.93953 0.13325 0.80265 0.11384 55576.493680 0.000764 0.08094 0.00879 0.99242 0 10.60990 0.31128 9.05985 0.26580 0.85875 0.08982 0.73326 0.07669
