/* ** ** 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 59202.163494 0.000362 0.19321 0.01531 0.99200 0 18.33822 0.58147 16.40265 0.52012 3.54322 0.25737 3.17211 0.23038 59202.164186 0.000330 0.19860 0.01624 0.99123 0 19.43273 0.63637 17.19478 0.56297 3.85939 0.28918 3.41759 0.25601 59202.164811 0.000295 0.24618 0.01973 0.99020 0 18.11745 0.64649 16.05051 0.57271 4.46019 0.32013 3.95227 0.28365 59202.165462 0.000356 0.18972 0.01500 0.97561 0 19.32858 0.60370 17.28078 0.53973 3.66697 0.26633 3.27784 0.23806 59202.166199 0.000382 0.17728 0.01388 0.99242 0 18.92914 0.57632 17.01636 0.51808 3.35578 0.24209 3.01659 0.21762 59202.166897 0.000315 0.23017 0.01854 0.98165 0 17.77482 0.61977 15.97055 0.55686 4.09125 0.29714 3.67609 0.26698 59202.167536 0.000324 0.21705 0.01725 0.99107 0 18.44856 0.61906 16.57795 0.55629 4.00418 0.28854 3.59776 0.25925 59202.168176 0.000315 0.20846 0.01644 1.00000 0 19.77629 0.65392 17.66415 0.58408 4.12263 0.29508 3.68058 0.26348 59202.168873 0.000382 0.17783 0.01385 0.99242 0 19.23470 0.58056 17.12952 0.51699 3.42050 0.24556 3.04717 0.21869 59202.169594 0.000339 0.20433 0.01618 1.00000 0 18.54577 0.60532 16.50779 0.53880 3.78944 0.27335 3.37754 0.24366 59202.170274 0.000341 0.19685 0.01569 1.00000 0 19.00054 0.61154 16.93762 0.54516 3.74023 0.27281 3.33486 0.24319 59202.170942 0.000327 0.22547 0.01781 0.98230 0 17.73510 0.60743 15.93678 0.54584 3.99865 0.28464 3.59311 0.25577 59202.171631 0.000362 0.19331 0.01540 0.97600 0 18.46895 0.58492 16.60094 0.52576 3.57017 0.26104 3.20910 0.23464 59202.172447 0.000454 0.20665 0.01421 0.99363 0 18.66335 0.52443 16.70366 0.46934 3.85674 0.24204 3.45155 0.21661
