/* ** ** 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 59734.008330 0.000421 0.16170 0.02442 0.99889 1 19.72920 1.13220 4.40915 0.25301 3.19019 0.44561 0.71318 0.09962 59734.009668 0.000402 0.12887 0.00984 1.00000 0 23.80515 0.61544 22.11605 0.57177 3.06775 0.22031 2.85008 0.20468 59734.010519 0.000448 0.12000 0.00923 0.97419 0 23.38395 0.58202 21.72460 0.54072 2.80613 0.20415 2.60701 0.18967 59734.011407 0.000440 0.11638 0.00877 0.99342 0 24.47929 0.59687 22.74323 0.55454 2.84885 0.20302 2.64680 0.18862 59734.012275 0.000428 0.12253 0.00935 1.00000 0 23.54386 0.59626 21.87325 0.55395 2.88485 0.20772 2.68015 0.19298 59734.013080 0.000376 0.14465 0.01108 0.99231 0 22.93862 0.63240 21.31083 0.58753 3.31811 0.23706 3.08266 0.22024 59734.013852 0.000396 0.13553 0.01053 1.00000 0 22.70471 0.60546 21.09400 0.56251 3.07709 0.22446 2.85879 0.20854 59734.014642 0.000394 0.13614 0.01040 0.97059 0 23.88025 0.62408 22.18515 0.57978 3.25095 0.23347 3.02019 0.21690 59734.015438 0.000402 0.13139 0.01008 0.98561 0 23.59941 0.61486 21.92427 0.57122 3.10082 0.22385 2.88072 0.20796 59734.016231 0.000391 0.13475 0.01053 0.98519 0 23.46315 0.62217 21.79757 0.57800 3.16168 0.23242 2.93725 0.21593 59734.016977 0.000356 0.14864 0.01145 0.99532 0 23.58312 0.65882 21.90849 0.61204 3.50533 0.25174 3.25641 0.23386
