/* ** ** 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 56408.327093 0.000298 0.15353 0.01194 0.99029 0 28.40741 0.79952 25.23554 0.71016 4.36128 0.31614 3.87495 0.28082 56408.327709 0.000318 0.12981 0.01002 0.99091 0 31.51593 0.81490 27.97500 0.72333 4.09122 0.29771 3.62745 0.26398 56408.328372 0.000344 0.12742 0.00968 0.99160 0 30.01127 0.76834 26.52789 0.67910 3.82412 0.27336 3.38099 0.24172 56408.329298 0.000582 0.13511 0.00768 0.99509 0 30.39821 0.59125 27.05655 0.52620 4.10708 0.21930 3.65170 0.19496 56408.388008 0.000286 0.15803 0.01235 1.00000 0 27.91647 0.80519 25.15756 0.72557 4.41161 0.32039 3.97414 0.28849 56408.388610 0.000315 0.14026 0.01111 1.00000 0 28.11367 0.76625 25.38068 0.69171 3.94312 0.29315 3.56163 0.26475 56408.389299 0.000373 0.12425 0.00941 0.97674 0 28.24443 0.70680 25.49344 0.63795 3.50939 0.25077 3.16712 0.22632 56408.389996 0.000324 0.13833 0.01065 1.00000 0 28.28316 0.75692 25.65480 0.68658 3.91228 0.28252 3.54863 0.25626 56408.390659 0.000339 0.12464 0.00974 1.00000 0 29.49181 0.75644 26.74569 0.68600 3.67579 0.27144 3.33354 0.24617 56408.391336 0.000339 0.12879 0.00996 1.00000 0 28.81818 0.74807 26.12397 0.67813 3.71138 0.27048 3.36442 0.24520 56408.391967 0.000292 0.15321 0.01190 0.99010 0 28.49702 0.80079 25.80847 0.72524 4.36617 0.31615 3.95444 0.28631 56408.392557 0.000298 0.14141 0.01103 1.00000 0 29.79367 0.81184 26.91487 0.73341 4.21319 0.30793 3.80227 0.27784 56408.393173 0.000318 0.13901 0.01062 0.98182 0 29.15567 0.77316 26.44733 0.70134 4.05285 0.29036 3.67642 0.26339 56408.393818 0.000327 0.12734 0.00981 1.00000 0 30.13988 0.77819 27.34316 0.70598 3.83791 0.27860 3.48177 0.25275 56408.394475 0.000330 0.13008 0.01003 1.00000 0 29.24783 0.76294 26.53213 0.69210 3.80442 0.27617 3.45123 0.25053 56408.395150 0.000344 0.13064 0.01018 0.99160 0 28.46243 0.74676 25.42623 0.66710 3.71838 0.27276 3.32060 0.24360 56408.395997 0.000503 0.12028 0.00771 1.00000 0 29.48137 0.61914 26.74339 0.56164 3.54607 0.21474 3.21676 0.19480
