/* ** ** 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 57737.002760 0.000436 0.18669 0.04364 0.99892 1 7.75165 0.74293 1.57139 0.15060 1.44717 0.30854 0.29362 0.06260 57737.004081 0.000370 0.11804 0.01812 0.96875 0 7.80722 0.38000 6.76441 0.32925 0.92157 0.13419 0.79861 0.11630 57737.004876 0.000425 0.10143 0.01506 0.98639 0 7.93476 0.35922 6.80270 0.30797 0.80485 0.11383 0.69080 0.09769 57737.005718 0.000417 0.10792 0.01605 0.95139 0 7.84599 0.36116 6.76860 0.31157 0.84674 0.11975 0.73114 0.10340 57737.006613 0.000477 0.09102 0.01347 0.99394 0 7.81117 0.33951 6.72250 0.29221 0.71095 0.10055 0.61077 0.08638 57737.007472 0.000382 0.10674 0.01628 0.97727 0 8.27146 0.38712 7.11486 0.33295 0.88292 0.12818 0.76024 0.11041 57737.008273 0.000420 0.11135 0.01681 0.95862 0 7.39865 0.35071 6.40706 0.30367 0.82383 0.11805 0.71309 0.10219 57737.009043 0.000350 0.11611 0.01737 0.99174 0 8.22892 0.40237 7.18918 0.35153 0.95544 0.13512 0.83472 0.11805 57737.009697 0.000304 0.12866 0.01984 1.00000 0 8.30998 0.43077 7.25943 0.37631 1.06914 0.15527 0.93401 0.13565 57737.010409 0.000408 0.09135 0.01403 0.97872 0 8.83775 0.38642 7.68475 0.33602 0.80734 0.11882 0.70307 0.10349 57737.011216 0.000399 0.10402 0.01608 0.99275 0 7.83440 0.36628 6.78233 0.31708 0.81496 0.12005 0.70820 0.10424 57737.012044 0.000428 0.09411 0.01411 0.97973 0 8.35892 0.36856 7.26942 0.32049 0.78668 0.11273 0.68358 0.09796 57737.012834 0.000362 0.12804 0.01824 0.99200 0 8.24612 0.39815 7.11380 0.34348 1.05581 0.14150 0.91244 0.12227
