/* ** ** 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 56629.530542 0.000350 0.18777 0.01474 1.00000 0 22.81059 0.71921 17.51414 0.54873 4.28321 0.30802 3.31395 0.23630 56629.531266 0.000373 0.17382 0.01377 0.98450 0 22.67663 0.68451 17.72515 0.53445 3.94176 0.28868 3.08230 0.22543 56629.531937 0.000298 0.21485 0.01711 1.00000 0 21.59568 0.72721 17.85877 0.60138 4.63982 0.33477 3.83629 0.27680 56629.532620 0.000385 0.16364 0.01290 0.98496 0 22.35752 0.65390 18.36272 0.53708 3.65853 0.26790 3.00470 0.22006 56629.533410 0.000405 0.16007 0.01265 0.97857 0 21.61362 0.62201 17.72795 0.51017 3.45965 0.25473 2.84386 0.20941 56629.534202 0.000388 0.15850 0.01269 0.98507 0 22.46834 0.64940 18.42468 0.53248 3.56112 0.26589 2.92366 0.21823 56629.534975 0.000385 0.18205 0.01414 0.96992 0 20.56130 0.62320 16.98952 0.51495 3.74314 0.26758 3.09290 0.22110 56629.535695 0.000336 0.20187 0.01570 0.99138 0 21.29786 0.68333 17.31650 0.55554 4.29949 0.30453 3.50288 0.24811 56629.536375 0.000344 0.17158 0.01419 1.00000 0 22.43073 0.69135 18.53665 0.57133 3.84876 0.29527 3.18111 0.24405 56629.537026 0.000307 0.20206 0.01591 1.00000 0 22.51802 0.73418 18.53450 0.60432 4.55009 0.32608 3.74511 0.26841 56629.537701 0.000367 0.16346 0.01307 1.00000 0 22.85891 0.68095 18.77033 0.55922 3.73663 0.27734 3.07032 0.22792 56629.538410 0.000341 0.18504 0.01467 0.99153 0 22.24786 0.68954 18.18345 0.56353 4.11683 0.30040 3.36287 0.24530 56629.539116 0.000365 0.16468 0.01319 1.00000 0 22.88491 0.67530 18.71726 0.55224 3.76869 0.28056 3.07878 0.22918 56629.539865 0.000385 0.17871 0.01412 0.99248 0 20.36968 0.62658 16.75884 0.51550 3.64032 0.26484 2.99590 0.21795 56629.540606 0.000356 0.16509 0.01305 1.00000 0 23.64786 0.69856 19.49018 0.57574 3.90413 0.28632 3.21772 0.23598 56629.541306 0.000344 0.18307 0.01428 0.99160 0 22.45570 0.69306 18.37842 0.56718 4.11104 0.29462 3.36425 0.24111 56629.541992 0.000341 0.17193 0.01365 1.00000 0 23.51165 0.71057 19.30601 0.58344 4.04244 0.29683 3.31875 0.24372 56629.543028 0.000694 0.16826 0.00960 1.00000 0 23.18063 0.49524 18.85752 0.40285 3.90036 0.20645 3.17296 0.16795
