/* ** ** 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 59919.232241 0.000211 0.16475 0.01287 1.00000 0 36.97971 1.08378 32.87284 0.96342 6.09257 0.44120 5.41648 0.39224 59919.232664 0.000211 0.15142 0.01172 1.00000 0 39.97870 1.12418 35.75719 1.00547 6.05340 0.43660 5.41392 0.39049 59919.233101 0.000226 0.14768 0.01136 1.00000 0 38.80050 1.08181 34.47663 0.96120 5.73012 0.41060 5.09017 0.36471 59919.233529 0.000203 0.15426 0.01189 1.00000 0 41.04353 1.16510 36.76832 1.04374 6.33157 0.45366 5.67190 0.40640 59919.233940 0.000208 0.16631 0.01286 0.97222 0 38.07119 1.10981 34.10659 0.99424 6.33172 0.45367 5.67190 0.40640 59919.234443 0.000295 0.15776 0.01035 0.98582 0 39.70089 0.95302 35.57831 0.85406 6.26338 0.38220 5.61320 0.34252 59919.484127 0.000495 0.13732 0.01083 0.99415 0 39.55214 1.08956 16.69874 0.45660 5.43139 0.40150 2.30388 0.16915 59919.485047 0.000425 0.15188 0.01172 0.96599 0 42.04462 1.16961 18.39158 0.51148 6.38595 0.45973 2.79693 0.20126 59919.485941 0.000469 0.13218 0.01034 0.97531 0 42.17042 1.11117 18.59640 0.48944 5.57423 0.41051 2.46618 0.18156 59919.486760 0.000350 0.18992 0.01488 0.99174 0 38.89825 1.23290 17.46966 0.55302 7.38763 0.52950 3.30830 0.23708 59919.487460 0.000350 0.17670 0.01381 0.98347 0 43.76162 1.32239 18.98184 0.57326 7.73247 0.55743 3.35577 0.24183 59919.488215 0.000405 0.16358 0.01274 0.97857 0 39.13604 1.13971 17.68795 0.51456 6.40194 0.46223 2.88439 0.20810 59919.489008 0.000388 0.16194 0.01275 1.00000 0 40.12781 1.18122 18.22237 0.53630 6.49839 0.47467 2.95273 0.21563 59919.489833 0.000437 0.14771 0.01141 0.98675 0 40.39072 1.12363 18.02582 0.50076 5.96599 0.42986 2.66553 0.19181 59919.490724 0.000454 0.14386 0.01125 0.99363 0 38.36048 1.06605 17.52094 0.48639 5.51844 0.40345 2.52240 0.18396 59919.491662 0.000483 0.13589 0.01058 0.99401 0 39.34603 1.05963 17.39066 0.46806 5.34675 0.39078 2.37045 0.17287 59919.492599 0.000454 0.16808 0.01241 0.98089 0 39.66158 1.10819 17.31547 0.48367 6.66640 0.45578 2.92049 0.19943
