/* ** ** 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 59735.002760 0.000436 0.17563 0.02731 0.99892 1 16.96659 1.03469 3.76120 0.22936 2.97989 0.42620 0.66039 0.09446 59735.004110 0.000399 0.13871 0.01053 0.96377 0 23.47584 0.61857 21.66451 0.57084 3.25626 0.23186 3.00641 0.21407 59735.004894 0.000385 0.14050 0.01092 1.00000 0 22.87932 0.62531 20.99380 0.57367 3.21447 0.23396 2.94899 0.21459 59735.005707 0.000428 0.12551 0.00972 0.97297 0 23.49951 0.59725 21.60742 0.54917 2.94936 0.21564 2.71394 0.19844 59735.006549 0.000414 0.13543 0.01022 0.98601 0 22.72255 0.59893 20.99664 0.55344 3.07734 0.21761 2.84161 0.20093 59735.007391 0.000428 0.13390 0.01022 0.97973 0 22.38205 0.58498 20.42731 0.53391 2.99691 0.21499 2.73408 0.19611 59735.008221 0.000402 0.13459 0.01025 0.98561 0 23.43443 0.61393 21.61594 0.56622 3.15396 0.22564 2.90836 0.20808 59735.009055 0.000431 0.12471 0.00954 1.00000 0 22.93113 0.58565 21.25838 0.54293 2.85984 0.20612 2.65123 0.19108 59735.010290 0.000804 0.13084 0.00748 0.97994 0 21.72692 0.42039 19.99982 0.38692 2.84276 0.15304 2.61552 0.14077
