/* ** ** 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 55360.069277 0.000362 0.19392 0.02741 0.98400 0 5.57627 0.31653 5.07860 0.28829 1.08136 0.13999 0.98489 0.12750 55360.070006 0.000367 0.15141 0.02297 0.96850 0 5.98150 0.32812 5.38609 0.29543 0.90567 0.12809 0.81436 0.11517 55360.070671 0.000298 0.17880 0.02725 1.00000 0 6.19790 0.37258 5.54430 0.33329 1.10816 0.15518 0.99194 0.13890 55360.071403 0.000434 0.18609 0.02379 0.99333 0 5.93379 0.30200 5.31943 0.27070 1.10424 0.12952 0.98782 0.11588 55360.072193 0.000356 0.14137 0.02139 1.00000 0 6.39580 0.34382 5.76072 0.30969 0.90417 0.12788 0.81436 0.11517 55360.072905 0.000356 0.14174 0.02200 0.99187 0 6.32861 0.34420 5.67588 0.30872 0.89702 0.13038 0.80363 0.11676 55360.073608 0.000347 0.16950 0.02490 0.97500 0 6.33702 0.35082 5.69767 0.31537 1.07414 0.14613 0.96587 0.13135 55360.074372 0.000417 0.13204 0.01969 0.95833 0 6.31618 0.31546 5.65150 0.28223 0.83398 0.11717 0.74718 0.10497 55360.075133 0.000344 0.15501 0.02448 0.97479 0 6.00244 0.34173 5.38469 0.30658 0.93047 0.13709 0.83604 0.12314 55360.075909 0.000431 0.12690 0.01906 0.95973 0 6.19640 0.31354 5.51023 0.27883 0.78629 0.11120 0.70047 0.09906 55360.076678 0.000339 0.16203 0.02475 0.98291 0 6.06164 0.34976 5.39070 0.31102 0.98215 0.13890 0.87102 0.12318 55360.077321 0.000304 0.17308 0.02635 1.00000 0 6.33374 0.37177 5.67000 0.33275 1.09622 0.15397 0.98201 0.13795 55360.078056 0.000431 0.11917 0.01785 0.99329 0 6.37431 0.31427 5.68741 0.28039 0.75961 0.10743 0.67680 0.09571 55360.078822 0.000336 0.15809 0.02533 0.96552 0 6.11950 0.34908 5.46577 0.31175 0.96742 0.14483 0.86482 0.12949 55360.079491 0.000333 0.16826 0.02576 0.99130 0 5.88111 0.34437 5.22429 0.30588 0.98958 0.13995 0.87866 0.12426 55360.080249 0.000420 0.12703 0.01908 0.98621 0 6.23530 0.31480 5.51403 0.27838 0.79209 0.11202 0.70047 0.09906 55360.081018 0.000350 0.15316 0.02446 0.95868 0 6.10489 0.34519 5.39887 0.30527 0.93502 0.13963 0.82688 0.12348 55360.081994 0.000625 0.15552 0.01817 0.94907 0 6.35960 0.26193 5.64099 0.23232 0.98907 0.10812 0.87715 0.09587
