/* ** ** 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 58266.437267 0.000431 0.22079 0.01742 0.98658 0 13.44065 0.44786 12.28079 0.40920 2.96750 0.21227 2.71099 0.19390 58266.438207 0.000509 0.17285 0.01341 0.98864 0 14.38976 0.42628 13.19220 0.39077 2.48732 0.17836 2.27881 0.16341 58266.439197 0.000480 0.18774 0.01449 0.99398 0 14.06448 0.43420 12.93453 0.39932 2.64045 0.18671 2.42828 0.17171 58266.440152 0.000475 0.18800 0.01460 0.99390 0 14.19361 0.44083 13.04984 0.40531 2.66841 0.18997 2.45338 0.17466 58266.441150 0.000524 0.17933 0.01407 0.97790 0 13.49201 0.40793 12.40462 0.37505 2.41954 0.17513 2.22453 0.16102 58266.442215 0.000541 0.16065 0.01225 0.99465 0 14.58279 0.41639 13.40877 0.38287 2.34277 0.16566 2.15412 0.15232 58266.443338 0.000582 0.15378 0.01177 0.98507 0 14.33854 0.39762 13.15586 0.36479 2.20499 0.15732 2.02282 0.14431 58266.444394 0.000475 0.20869 0.01639 0.96951 0 13.10988 0.42578 12.00425 0.38981 2.73584 0.19567 2.50639 0.17927 58266.445375 0.000506 0.19523 0.01533 0.97143 0 13.03208 0.40754 11.98477 0.37479 2.54424 0.18320 2.33970 0.16847 58266.446405 0.000524 0.17099 0.01334 1.00000 0 13.88441 0.41472 12.76681 0.38134 2.37415 0.17104 2.18303 0.15727 58266.447750 0.000822 0.18695 0.01158 0.99296 0 13.17408 0.32171 12.11389 0.29582 2.46284 0.14020 2.26461 0.12891
