/* ** ** 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 55549.515591 0.000570 0.09805 0.01472 0.73095 0 8.20050 0.36599 7.02222 0.31328 0.80409 0.11523 0.68838 0.09864 55549.516505 0.000344 0.11171 0.01754 1.00000 0 8.39058 0.41101 7.22014 0.35368 0.93734 0.13981 0.80671 0.12032 55549.517260 0.000411 0.10010 0.01562 0.97183 0 8.08121 0.37157 6.94884 0.31950 0.80896 0.12066 0.69564 0.10376 55549.518097 0.000425 0.09096 0.01378 0.97959 0 8.69897 0.37613 7.48806 0.32378 0.79127 0.11490 0.68113 0.09890 55549.518976 0.000454 0.08720 0.01287 0.98726 0 8.61049 0.36356 7.41077 0.31290 0.75081 0.10618 0.64624 0.09139 55549.519838 0.000408 0.09847 0.01478 0.97872 0 8.47783 0.37897 7.29441 0.32607 0.83484 0.11963 0.71830 0.10293 55549.520692 0.000446 0.09363 0.01438 0.97403 0 8.03255 0.35425 6.90938 0.30471 0.75212 0.11068 0.64694 0.09520 55549.521525 0.000388 0.10624 0.01598 0.94776 0 8.53038 0.39062 7.34634 0.33640 0.90628 0.12987 0.78051 0.11184 55549.522263 0.000350 0.10721 0.01637 0.98347 0 8.93083 0.42185 7.68872 0.36318 0.95750 0.13904 0.82423 0.11968 55549.522984 0.000370 0.11412 0.01749 1.00000 0 7.80052 0.38295 6.71541 0.32967 0.89016 0.12926 0.76627 0.11127 55549.523742 0.000388 0.10223 0.01523 0.98507 0 8.70373 0.39671 7.49245 0.34150 0.88975 0.12621 0.76612 0.10867 55549.524509 0.000379 0.11264 0.01703 0.99237 0 7.85419 0.37843 6.76940 0.32617 0.88473 0.12678 0.76250 0.10926 55549.525232 0.000344 0.11553 0.01770 0.97479 0 8.48992 0.41595 7.31927 0.35860 0.98081 0.14242 0.84554 0.12278 55549.525958 0.000382 0.09473 0.01438 0.98485 0 9.33048 0.41207 7.97173 0.35206 0.88385 0.12836 0.75448 0.10956 55549.526693 0.000347 0.10016 0.01487 0.99167 0 9.80056 0.44135 8.40130 0.37831 0.98162 0.13883 0.84174 0.11904
