/* ** ** 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 55250.312743 0.000321 0.35830 0.01348 0.99099 0 56.12531 1.08050 50.15380 0.96550 20.10957 0.64969 17.97473 0.58082 55250.313385 0.000321 0.36059 0.01370 1.00000 0 55.63649 1.08394 49.38051 0.96207 20.06209 0.65429 17.80337 0.58075 55250.314004 0.000298 0.38784 0.01494 1.00000 0 55.95185 1.13325 49.17834 0.99602 21.70024 0.71115 19.07909 0.62533 55250.314647 0.000344 0.34015 0.01271 0.99160 0 56.39682 1.05850 49.25869 0.92453 19.18363 0.61989 16.75611 0.54145 55250.315321 0.000330 0.34032 0.01270 1.00000 0 58.57903 1.10111 51.42039 0.96650 19.93590 0.64248 17.49333 0.56381 55250.315960 0.000310 0.38365 0.01462 1.00000 0 55.23240 1.11324 48.23859 0.97228 21.19007 0.68546 18.50670 0.59865 55250.316588 0.000318 0.36120 0.01356 1.00000 0 56.99620 1.10424 50.04531 0.96962 20.58706 0.66215 18.07498 0.58132 55250.317225 0.000318 0.35530 0.01345 1.00000 0 57.35165 1.10798 50.40363 0.97366 20.37683 0.66342 17.91075 0.58304 55250.317887 0.000344 0.33181 0.01239 1.00000 0 57.37728 1.06831 50.09900 0.93279 19.03859 0.61618 16.62364 0.53802 55250.318570 0.000339 0.34913 0.01302 1.00000 0 55.96347 1.06829 48.84680 0.93244 19.53853 0.62610 17.05358 0.54647 55250.319245 0.000336 0.34216 0.01285 1.00000 0 56.95616 1.08193 49.74190 0.94489 19.48792 0.63138 17.01902 0.55139 55250.319919 0.000339 0.33990 0.01285 1.00000 0 56.53605 1.06883 49.33954 0.93278 19.21688 0.62920 16.77052 0.54910 55250.320590 0.000333 0.35370 0.01340 1.00000 0 55.45379 1.06944 48.41253 0.93365 19.61375 0.63982 17.12323 0.55858 55250.321241 0.000318 0.36507 0.01382 1.00000 0 56.34351 1.10313 49.16295 0.96254 20.56911 0.66641 17.94733 0.58147 55250.321898 0.000339 0.35245 0.01320 1.00000 0 55.25566 1.05976 48.21667 0.92476 19.47486 0.62634 16.99357 0.54654 55250.322595 0.000359 0.32809 0.01226 1.00000 0 55.68231 1.03214 48.59979 0.90086 18.26897 0.59252 15.94518 0.51715 55250.323310 0.000356 0.34144 0.01278 1.00000 0 54.08654 1.02000 47.20029 0.89013 18.46732 0.59706 16.11561 0.52103 55250.324022 0.000356 0.33431 0.01227 1.00000 0 55.70274 1.03215 48.85880 0.90530 18.62177 0.59022 16.33600 0.51775 55250.325020 0.000642 0.36292 0.00984 1.00000 0 54.57511 0.76071 47.89272 0.66753 19.80623 0.46057 17.37493 0.40402
