/* ** ** 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 57482.020533 0.000362 0.15390 0.01216 1.00000 0 21.83448 0.62057 20.19578 0.57400 3.36041 0.24782 3.10831 0.22923 57482.021323 0.000428 0.13239 0.01017 1.00000 0 21.91354 0.57356 20.26650 0.53045 2.90110 0.20949 2.68307 0.19374 57482.022116 0.000365 0.15835 0.01246 1.00000 0 21.60243 0.62420 19.67427 0.56848 3.42078 0.25031 3.11158 0.22765 57482.022871 0.000391 0.14480 0.01105 0.99259 0 22.70599 0.61876 20.59904 0.56133 3.28773 0.23433 2.98237 0.21256 57482.023682 0.000420 0.13588 0.01044 0.97931 0 22.14272 0.58255 20.44545 0.53789 3.00878 0.21725 2.77889 0.20066 57482.024483 0.000382 0.15286 0.01175 0.99242 0 21.88105 0.61146 19.90936 0.55627 3.34484 0.23961 3.03910 0.21773 57482.025316 0.000451 0.12688 0.00967 0.99359 0 22.05142 0.56306 20.14478 0.51438 2.79790 0.20098 2.55561 0.18357 57482.026161 0.000394 0.14686 0.01114 0.99265 0 22.16454 0.60649 20.20942 0.55295 3.25507 0.23017 2.96790 0.20986 57482.026905 0.000350 0.16163 0.01263 1.00000 0 21.82343 0.63338 20.10283 0.58346 3.52725 0.25601 3.24865 0.23581 57482.027651 0.000396 0.14724 0.01148 0.98540 0 21.77341 0.59666 19.94696 0.54656 3.20596 0.23399 2.93743 0.21432 57482.028592 0.000544 0.14045 0.00958 0.99359 0 21.16042 0.50457 19.38217 0.46210 2.97192 0.19003 2.72091 0.17393
