/* ** ** 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 59734.924362 0.000339 0.14476 0.01110 0.99145 0 25.76315 0.70494 23.63708 0.64670 3.72958 0.26705 3.42376 0.24517 59734.925033 0.000333 0.14863 0.01133 0.98261 0 25.50646 0.69925 23.75199 0.65115 3.79112 0.26977 3.53019 0.25120 59734.925725 0.000359 0.13680 0.01064 1.00000 0 24.93917 0.66851 23.11336 0.61957 3.41159 0.24900 3.16041 0.23066 59734.926492 0.000408 0.12078 0.00917 0.99291 0 25.37226 0.63129 23.62110 0.58772 3.06442 0.21970 2.85291 0.20453 59734.927215 0.000315 0.15103 0.01189 1.00000 0 25.45211 0.72163 23.69872 0.67192 3.84414 0.28236 3.57922 0.26290 59734.927886 0.000356 0.13649 0.01072 0.99187 0 25.18026 0.68383 23.44388 0.63668 3.43678 0.25336 3.19986 0.23590 59734.928610 0.000367 0.13570 0.01036 0.98425 0 25.23927 0.66985 23.38754 0.62060 3.42509 0.24526 3.17725 0.22752 59734.929385 0.000408 0.12474 0.00947 0.98582 0 24.68950 0.62478 22.89486 0.57939 3.07987 0.22054 2.85724 0.20460 59734.930158 0.000365 0.14185 0.01099 0.98413 0 24.04044 0.65647 22.37860 0.61109 3.41023 0.24732 3.17456 0.23023 59734.930896 0.000373 0.13531 0.01052 0.97674 0 24.79119 0.66199 22.97889 0.61364 3.35452 0.24483 3.11024 0.22700 59734.931622 0.000353 0.13808 0.01075 1.00000 0 25.25313 0.68504 23.27165 0.63116 3.48707 0.25443 3.21222 0.23444 59734.932322 0.000347 0.14273 0.01097 0.99167 0 25.25478 0.68905 23.39342 0.63823 3.60450 0.25906 3.33953 0.24004 59734.933349 0.000680 0.13779 0.00778 0.99574 0 24.84715 0.48368 23.07546 0.44919 3.42379 0.18159 3.17827 0.16857
