/* ** ** 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 54938.982783 0.000292 0.16279 0.01250 0.99010 0 26.32830 0.75251 24.63984 0.70425 4.28606 0.30542 4.01119 0.28583 54938.983379 0.000304 0.16591 0.01274 0.98095 0 24.94204 0.71996 23.34248 0.67379 4.13809 0.29449 3.87271 0.27560 54938.984212 0.000530 0.17474 0.00975 0.98489 0 26.06246 0.55776 24.39105 0.52199 4.55417 0.23459 4.26211 0.21955 54939.026014 0.000315 0.15375 0.01186 0.98165 0 25.63103 0.71606 24.07065 0.67247 3.94070 0.28322 3.70080 0.26598 54939.026642 0.000312 0.16209 0.01268 0.99074 0 24.12058 0.69860 22.65215 0.65607 3.90965 0.28407 3.67164 0.26678 54939.027267 0.000312 0.16070 0.01232 1.00000 0 24.63680 0.70397 23.13696 0.66111 3.95910 0.28157 3.71808 0.26443 54939.027852 0.000272 0.18407 0.01431 0.98936 0 24.72915 0.75556 23.22367 0.70956 4.55179 0.32537 4.27468 0.30556 54939.028413 0.000289 0.17845 0.01369 1.00000 0 24.17354 0.72749 22.70189 0.68320 4.31377 0.30439 4.05116 0.28586 54939.029290 0.000587 0.14942 0.00856 0.99160 0 25.58747 0.52578 24.02974 0.49377 3.82319 0.20435 3.59044 0.19191 54939.092726 0.000356 0.14385 0.01111 1.00000 0 23.74572 0.64976 22.29992 0.61020 3.41573 0.24669 3.20776 0.23167 54939.093397 0.000315 0.16305 0.01269 1.00000 0 23.78876 0.68929 22.34034 0.64732 3.87867 0.28015 3.64251 0.26309 54939.094051 0.000339 0.16181 0.01243 0.98291 0 22.86692 0.65649 21.47463 0.61651 3.70019 0.26375 3.47490 0.24769 54939.094688 0.000298 0.16858 0.01319 1.00000 0 24.22500 0.71754 22.75002 0.67386 4.08390 0.29574 3.83524 0.27774 54939.095296 0.000310 0.16621 0.01293 1.00000 0 23.74404 0.69597 22.29834 0.65359 3.94643 0.28428 3.70615 0.26697 54939.095950 0.000344 0.14869 0.01148 1.00000 0 23.86461 0.66116 22.41158 0.62091 3.54847 0.25561 3.33242 0.24005 54939.096638 0.000344 0.15289 0.01178 0.99160 0 23.37834 0.65179 21.95491 0.61211 3.57425 0.25678 3.35663 0.24114 54939.097321 0.000339 0.14690 0.01150 1.00000 0 24.28480 0.67336 22.80618 0.63236 3.56741 0.26110 3.35021 0.24520 54939.097934 0.000275 0.19383 0.01496 1.00000 0 23.42844 0.73390 22.00196 0.68921 4.54122 0.32039 4.26472 0.30088 54939.098727 0.000518 0.16229 0.01003 1.00000 0 23.14097 0.53118 21.73200 0.49884 3.75560 0.21558 3.52693 0.20246
