/* ** ** 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 58494.104401 0.000512 0.18020 0.01416 0.99435 0 19.21033 0.58757 12.50309 0.38211 3.46167 0.25050 2.25758 0.16312 58494.105411 0.000498 0.19614 0.01582 0.99419 0 18.08628 0.58489 11.65605 0.37696 3.54743 0.26206 2.27968 0.16850 58494.106346 0.000437 0.21469 0.01750 0.99338 0 18.59167 0.63110 12.04246 0.40877 3.99139 0.29579 2.58548 0.19163 58494.107275 0.000492 0.18328 0.01432 0.99412 0 19.80080 0.61490 12.83009 0.39841 3.62915 0.26009 2.34910 0.16834 58494.108258 0.000492 0.18700 0.01498 0.99412 0 19.19785 0.60636 12.32643 0.38929 3.59008 0.26429 2.30566 0.16974 58494.109260 0.000509 0.19496 0.01540 0.99432 0 18.13254 0.58165 11.60905 0.37235 3.53507 0.25511 2.25807 0.16291 58494.110293 0.000524 0.17919 0.01412 0.98343 0 19.50227 0.59567 12.32903 0.37654 3.49456 0.25381 2.20970 0.16050 58494.111401 0.000584 0.16927 0.01318 0.99505 0 18.51389 0.55035 11.67050 0.34688 3.13392 0.22552 1.97595 0.14219 58494.112535 0.000550 0.17472 0.01411 0.98421 0 19.21747 0.58824 11.87892 0.36362 3.35758 0.25083 2.07572 0.15508 58494.113588 0.000503 0.21269 0.01676 0.95977 0 18.14052 0.59419 11.17001 0.36581 3.85832 0.27651 2.37723 0.17036 58494.114601 0.000509 0.19687 0.01602 0.97727 0 18.43811 0.59881 11.39945 0.37022 3.62997 0.27089 2.24411 0.16746 58494.115886 0.000775 0.18718 0.01268 0.98507 0 17.84656 0.47292 11.11857 0.29459 3.34052 0.20822 2.07801 0.12954
