/* ** ** 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 58172.321809 0.000362 0.19111 0.01478 0.99200 0 23.24750 0.72578 17.16779 0.53558 4.44292 0.31441 3.28239 0.23226 58172.322536 0.000365 0.17345 0.01418 0.98413 0 22.93724 0.70882 17.75968 0.54890 3.97847 0.30101 3.08330 0.23322 58172.323259 0.000359 0.17584 0.01373 0.99194 0 23.46820 0.71218 18.37394 0.55757 4.12657 0.29696 3.22902 0.23235 58172.323942 0.000324 0.18471 0.01469 1.00000 0 24.30066 0.76190 18.92382 0.59314 4.48857 0.32811 3.49552 0.25559 58172.324619 0.000353 0.17703 0.01383 1.00000 0 23.61180 0.71841 18.45540 0.56140 4.18002 0.30072 3.25548 0.23426 58172.325319 0.000347 0.17649 0.01374 1.00000 0 23.73525 0.72188 18.74732 0.57013 4.18893 0.30018 3.30833 0.23708 58172.325982 0.000315 0.20214 0.01609 0.99083 0 22.71688 0.73976 17.99949 0.58612 4.59201 0.33349 3.64196 0.26452 58172.326633 0.000336 0.19144 0.01508 0.98276 0 22.98642 0.72616 18.13361 0.57283 4.40060 0.31742 3.46637 0.25008 58172.327316 0.000347 0.17883 0.01411 1.00000 0 23.17690 0.71286 18.34328 0.56413 4.14478 0.30105 3.27777 0.23807 58172.327981 0.000318 0.19333 0.01580 1.00000 0 22.93875 0.74756 18.16547 0.59199 4.43470 0.33225 3.51060 0.26300 58172.328618 0.000318 0.19915 0.01561 0.99091 0 23.01453 0.74116 18.37513 0.59174 4.58327 0.32760 3.66058 0.26165 58172.329263 0.000327 0.18977 0.01496 1.00000 0 23.33477 0.74117 18.42258 0.58517 4.42831 0.31942 3.49704 0.25229 58172.329917 0.000327 0.18590 0.01479 1.00000 0 23.36622 0.73170 18.63997 0.58370 4.34388 0.31762 3.46459 0.25333 58172.330591 0.000347 0.18201 0.01426 1.00000 0 22.78276 0.70715 18.18348 0.56439 4.14676 0.29840 3.30974 0.23816 58172.331338 0.000399 0.16227 0.01249 0.99275 0 22.69415 0.66189 17.95140 0.52357 3.68268 0.26220 2.91119 0.20723 58172.332136 0.000399 0.17613 0.01319 0.98551 0 23.02797 0.66267 18.32665 0.52736 4.05600 0.28031 3.23344 0.22341
