/* ** ** 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 58899.224980 0.000396 0.16035 0.01319 0.95620 0 28.20040 0.83175 18.46662 0.52632 4.52189 0.34726 2.96643 0.22221 58899.225729 0.000353 0.15370 0.01199 1.00000 0 27.51263 0.78245 20.97147 0.59600 4.22871 0.30714 3.22489 0.23411 58899.226415 0.000333 0.15853 0.01261 0.98261 0 30.02094 0.86299 21.76715 0.62572 4.75923 0.35284 3.45322 0.25600 58899.227043 0.000295 0.18337 0.01464 0.98039 0 29.23632 0.90259 21.37542 0.65989 5.36106 0.39481 3.92021 0.28872 58899.227656 0.000318 0.16634 0.01303 0.99091 0 29.66016 0.87258 21.69605 0.63832 4.93373 0.35815 3.60951 0.26203 58899.228305 0.000330 0.16655 0.01310 0.98246 0 28.88710 0.85294 21.06948 0.62211 4.81101 0.35068 3.51458 0.25615 58899.228976 0.000341 0.15893 0.01234 0.99153 0 29.18192 0.84133 21.25330 0.61277 4.63781 0.33447 3.37816 0.24362 58899.229627 0.000310 0.16960 0.01315 0.98131 0 30.52034 0.90313 22.30597 0.66005 5.17617 0.37090 3.78145 0.27092 58899.230307 0.000370 0.14708 0.01134 1.00000 0 28.68204 0.79493 21.09106 0.58452 4.21866 0.30344 3.10350 0.22324 58899.230981 0.000304 0.18179 0.01472 1.00000 0 28.00611 0.88265 20.34026 0.64103 5.09118 0.37989 3.69911 0.27604 58899.231626 0.000341 0.16060 0.01238 1.00000 0 28.78304 0.82996 21.05324 0.60707 4.62241 0.33033 3.38183 0.24167 58899.232286 0.000318 0.17338 0.01373 0.99091 0 28.37441 0.86277 20.72693 0.63022 4.91960 0.35959 3.59293 0.26255 58899.232900 0.000295 0.18828 0.01482 1.00000 0 28.26114 0.89025 20.58396 0.64841 5.32112 0.38375 3.87495 0.27945 58899.233556 0.000362 0.15623 0.01215 0.97600 0 28.32162 0.80389 20.75296 0.58901 4.42465 0.32043 3.24131 0.23468 58899.234233 0.000315 0.18479 0.01444 0.99083 0 27.56767 0.85478 20.00086 0.62015 5.09424 0.36552 3.69677 0.26523 58899.234841 0.000292 0.18493 0.01452 1.00000 0 29.23199 0.90639 21.17480 0.65657 5.40582 0.38985 3.91331 0.28222 58899.235614 0.000480 0.16976 0.01103 1.00000 0 27.95605 0.69171 20.30348 0.50233 4.74580 0.28513 3.44536 0.20695
