/* ** ** 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 59203.033177 0.000304 0.23593 0.01903 1.00000 0 17.68624 0.62022 15.87331 0.55663 4.17271 0.30302 3.74623 0.27206 59203.033781 0.000301 0.23554 0.01898 0.99038 0 17.97785 0.62721 16.21363 0.56566 4.23447 0.30752 3.81897 0.27734 59203.034380 0.000298 0.23226 0.01864 0.98058 0 18.67985 0.64604 16.85426 0.58291 4.33849 0.31425 3.91443 0.28353 59203.034956 0.000278 0.24132 0.01906 1.00000 0 19.48288 0.68412 17.56896 0.61691 4.70168 0.33267 4.23987 0.30000 59203.035526 0.000292 0.24435 0.01937 0.97030 0 18.55941 0.65401 16.73934 0.58988 4.53494 0.32199 4.09023 0.29042 59203.036105 0.000286 0.25650 0.02051 1.00000 0 17.59497 0.64272 15.87130 0.57975 4.51303 0.32093 4.07092 0.28949 59203.036733 0.000341 0.19602 0.01568 0.96610 0 19.43641 0.61773 17.52916 0.55712 3.80989 0.27966 3.43598 0.25222 59203.037346 0.000272 0.25277 0.02097 0.98936 0 18.30386 0.67241 16.50730 0.60641 4.62664 0.34420 4.17253 0.31042 59203.037908 0.000289 0.24387 0.01963 1.00000 0 17.96861 0.64117 16.20449 0.57822 4.38205 0.31611 3.95182 0.28508 59203.038480 0.000284 0.23632 0.01898 1.00000 0 18.91820 0.66782 17.06395 0.60236 4.47071 0.32251 4.03247 0.29090 59203.039051 0.000286 0.24796 0.01983 0.98990 0 18.28735 0.65674 16.40279 0.58905 4.53461 0.32410 4.07157 0.29102 59203.039592 0.000255 0.27637 0.02227 1.00000 0 18.73923 0.70603 16.62248 0.62611 5.17888 0.36887 4.60454 0.32793 59203.040121 0.000275 0.24689 0.01985 1.00000 0 19.00186 0.68846 17.02805 0.61691 4.69128 0.33663 4.20199 0.30156 59203.040671 0.000275 0.24191 0.01929 0.98947 0 19.58724 0.69346 17.54647 0.62116 4.73843 0.33866 4.24483 0.30340 59203.041218 0.000272 0.25390 0.02005 1.00000 0 19.14846 0.68875 17.12822 0.61603 4.86185 0.34179 4.34953 0.30576 59203.041785 0.000295 0.23753 0.01906 0.98039 0 18.61333 0.65411 16.63137 0.58443 4.42123 0.31898 3.95182 0.28508 59203.042424 0.000344 0.20454 0.01615 0.99160 0 18.25335 0.59464 16.45789 0.53615 3.73348 0.26863 3.36598 0.24219 59203.043255 0.000486 0.24913 0.01504 1.00000 0 19.21604 0.51466 17.07617 0.45729 4.78724 0.25897 4.25455 0.23015
