/* ** ** 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 60050.846446 0.000252 0.15895 0.01224 0.98851 0 31.87174 0.90573 29.14353 0.82821 5.06615 0.36267 4.63248 0.33150 60050.846976 0.000278 0.14442 0.01111 1.00000 0 31.65557 0.86804 28.79852 0.78965 4.57179 0.32856 4.16197 0.29917 60050.847488 0.000234 0.15958 0.01242 1.00000 0 33.76253 0.97479 30.58068 0.88291 5.38768 0.38932 4.88324 0.35285 60050.847968 0.000246 0.16087 0.01242 1.00000 0 31.99842 0.92635 29.14189 0.84359 5.14743 0.36834 4.68698 0.33540 60050.848451 0.000237 0.17089 0.01329 0.98780 0 31.65287 0.94028 28.70540 0.85270 5.40923 0.38887 4.90084 0.35241 60050.848940 0.000252 0.15310 0.01186 1.00000 0 32.98349 0.93503 29.65219 0.84059 5.04977 0.36406 4.53982 0.32729 60050.849467 0.000275 0.14111 0.01099 1.00000 0 32.38872 0.88135 29.49752 0.80258 4.57045 0.33336 4.16077 0.30344 60050.849982 0.000240 0.17559 0.01368 1.00000 0 30.04862 0.91217 27.21413 0.82602 5.27628 0.37860 4.77579 0.34264 60050.850491 0.000269 0.14930 0.01142 0.98925 0 32.88386 0.89638 29.56843 0.80600 4.90952 0.35097 4.41453 0.31558 60050.850986 0.000226 0.17069 0.01349 1.00000 0 32.63890 0.97709 29.34453 0.87847 5.57115 0.40756 5.00882 0.36643 60050.851440 0.000229 0.16718 0.01297 1.00000 0 33.40488 0.97762 30.27078 0.88583 5.58475 0.40143 5.05759 0.36355 60050.851921 0.000252 0.16105 0.01244 0.98851 0 31.82869 0.91210 28.61963 0.82014 5.12601 0.36776 4.60919 0.33068 60050.852453 0.000281 0.14173 0.01079 1.00000 0 32.38217 0.87268 29.28510 0.78917 4.58968 0.32675 4.14846 0.29536 60050.852959 0.000226 0.17183 0.01326 1.00000 0 32.92083 0.97888 29.86888 0.88806 5.65688 0.40279 5.12589 0.36505 60050.853454 0.000269 0.13962 0.01080 1.00000 0 33.20557 0.90066 30.30669 0.82191 4.63604 0.33581 4.23160 0.30656 60050.853946 0.000223 0.19029 0.01443 0.97446 0 32.93811 0.99638 29.97551 0.90686 6.26795 0.43601 5.70644 0.39695
