/* ** ** 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 59346.207700 0.000535 0.15201 0.01157 0.99459 0 15.59553 0.43753 14.39604 0.40390 2.37060 0.16778 2.19017 0.15501 59346.208782 0.000547 0.13192 0.01016 0.98942 0 17.40094 0.45577 15.95391 0.41781 2.29560 0.16626 2.10663 0.15257 59346.209887 0.000558 0.13409 0.01037 0.99482 0 16.57494 0.43709 15.31934 0.40399 2.22249 0.16157 2.05344 0.14922 59346.211039 0.000593 0.13394 0.01015 0.98049 0 16.01034 0.41883 14.82010 0.38769 2.14443 0.15254 1.98500 0.14120 59346.212196 0.000564 0.13388 0.01043 0.97436 0 16.68213 0.43866 15.42913 0.40571 2.23344 0.16383 2.06789 0.15168 59346.213322 0.000561 0.13218 0.01027 0.99485 0 16.53285 0.43428 15.38862 0.40422 2.18533 0.15976 2.03409 0.14870 59346.214462 0.000579 0.12634 0.00966 0.99500 0 16.90626 0.43432 15.73608 0.40426 2.13588 0.15376 1.98805 0.14312 59346.215570 0.000530 0.14401 0.01114 1.00000 0 16.18086 0.44835 15.00593 0.41581 2.33019 0.16831 2.16362 0.15629 59346.216603 0.000503 0.15194 0.01168 0.99425 0 16.33496 0.45947 15.10412 0.42485 2.48200 0.17765 2.29655 0.16434 59346.217662 0.000556 0.13901 0.01073 0.97917 0 16.20123 0.43329 15.07401 0.40314 2.25208 0.16310 2.09542 0.15176 59346.219170 0.000952 0.13741 0.00814 0.99088 0 16.16653 0.33069 15.04682 0.30779 2.22138 0.12358 2.06751 0.11502
