/* ** ** 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 59318.933700 0.000396 0.15686 0.01201 0.97810 0 20.68486 0.57778 19.13240 0.53441 3.24469 0.23124 3.00156 0.21388 59318.934475 0.000379 0.16399 0.01283 0.99237 0 19.86714 0.58136 18.44456 0.53974 3.25806 0.23636 3.02477 0.21943 59318.935231 0.000376 0.16297 0.01277 0.99231 0 20.24810 0.59048 18.71178 0.54569 3.29978 0.24000 3.05220 0.22198 59318.935997 0.000391 0.15576 0.01208 0.99259 0 20.53926 0.58266 19.03403 0.53992 3.19916 0.23086 2.96438 0.21393 59318.936793 0.000405 0.16075 0.01262 0.98571 0 19.07023 0.55284 17.65793 0.51189 3.06550 0.22357 2.83863 0.20700 59318.937563 0.000365 0.17006 0.01328 0.97619 0 20.53270 0.60400 18.88933 0.55563 3.49176 0.25259 3.21320 0.23249 59318.938341 0.000414 0.15491 0.01196 0.99301 0 19.39780 0.54893 18.01089 0.50968 3.00498 0.21577 2.79013 0.20034 59318.939148 0.000394 0.15230 0.01193 1.00000 0 20.36846 0.58118 18.91285 0.53965 3.10206 0.22620 2.88037 0.21004 59318.939959 0.000417 0.14348 0.01107 0.98611 0 20.86486 0.56709 19.37352 0.52656 2.99361 0.21606 2.77964 0.20062 59318.940711 0.000336 0.18171 0.01405 0.99138 0 20.65434 0.63032 19.08153 0.58232 3.75311 0.26674 3.47111 0.24670 59318.941431 0.000385 0.15508 0.01226 1.00000 0 20.29929 0.58289 18.84805 0.54122 3.14801 0.23194 2.92295 0.21536 59318.942262 0.000446 0.13327 0.01038 0.98052 0 20.94282 0.54985 19.39382 0.50919 2.79113 0.20462 2.58438 0.18943 59318.943069 0.000362 0.16206 0.01248 0.98400 0 21.53960 0.61727 19.96213 0.57205 3.49080 0.24940 3.23324 0.23097 59318.943920 0.000489 0.15320 0.01082 0.98817 0 19.77788 0.50853 18.29666 0.47044 3.02990 0.19937 2.80123 0.18433
