/* ** ** 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 57163.917267 0.000394 0.14707 0.01146 0.97794 0 21.84151 0.59779 20.04814 0.54864 3.21217 0.23442 2.94665 0.21505 57163.918016 0.000356 0.16684 0.01283 1.00000 0 21.16616 0.62399 19.52441 0.57552 3.53142 0.25071 3.25949 0.23135 57163.918771 0.000399 0.13841 0.01074 1.00000 0 22.35098 0.59818 20.74627 0.55523 3.09364 0.22542 2.87074 0.20916 57163.919564 0.000394 0.15074 0.01181 0.99265 0 21.17158 0.60153 19.27298 0.54747 3.19130 0.23296 2.90300 0.21186 57163.920348 0.000391 0.14772 0.01134 0.99259 0 21.94291 0.60589 20.06893 0.55408 3.24150 0.23210 2.96390 0.21224 57163.921164 0.000425 0.13567 0.01035 0.99320 0 21.88373 0.57648 20.08485 0.52907 2.96886 0.21257 2.72029 0.19479 57163.921992 0.000402 0.14801 0.01142 0.98561 0 21.42338 0.59032 19.49628 0.53717 3.17086 0.22854 2.88620 0.20798 57163.922776 0.000382 0.14025 0.01099 1.00000 0 23.08801 0.62905 21.04656 0.57338 3.23803 0.23786 2.95570 0.21708 57163.923517 0.000359 0.16334 0.01292 0.99194 0 21.34263 0.62576 19.41858 0.56930 3.48602 0.25607 3.17197 0.23297 57163.924243 0.000367 0.16271 0.01262 1.00000 0 20.98223 0.61002 19.22254 0.55880 3.41395 0.24542 3.12924 0.22491 57163.924998 0.000388 0.15232 0.01172 1.00000 0 21.10927 0.58858 19.54948 0.54504 3.21537 0.23050 2.98072 0.21369 57163.925733 0.000347 0.16504 0.01285 1.00000 0 21.90560 0.64689 19.96823 0.58973 3.61532 0.26054 3.29508 0.23745 57163.926566 0.000486 0.17040 0.01115 0.98810 0 21.41223 0.53504 19.69904 0.49215 3.64866 0.22062 3.35952 0.20313
