/* ** ** 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 58100.249950 0.000318 0.21179 0.01684 1.00000 0 21.57442 0.71246 17.15404 0.56465 4.56923 0.33057 3.61198 0.26099 58100.250587 0.000318 0.22868 0.01815 0.99091 0 20.33043 0.69575 16.15806 0.55254 4.64911 0.33297 3.68037 0.26349 58100.251232 0.000327 0.20350 0.01662 1.00000 0 20.21291 0.66947 16.76416 0.55525 4.11340 0.30713 3.41554 0.25491 58100.251860 0.000301 0.22687 0.01808 1.00000 0 20.38117 0.71102 16.82673 0.58702 4.62393 0.33137 3.81720 0.27356 58100.252462 0.000301 0.22437 0.01792 1.00000 0 20.45799 0.70155 16.94051 0.58093 4.59011 0.33119 3.79952 0.27413 58100.253119 0.000356 0.18357 0.01451 1.00000 0 21.11265 0.65912 17.43432 0.54429 3.87561 0.28150 3.19765 0.23227 58100.253827 0.000353 0.19153 0.01491 0.99180 0 20.83384 0.65518 17.22528 0.54166 3.99023 0.28410 3.29610 0.23464 58100.254522 0.000341 0.20036 0.01580 1.00000 0 20.25660 0.65282 16.81263 0.54180 4.05852 0.29205 3.36571 0.24220 58100.255182 0.000318 0.20742 0.01624 0.99091 0 21.18522 0.69181 17.64527 0.57623 4.39419 0.31281 3.65897 0.26047 58100.255824 0.000324 0.20446 0.01650 1.00000 0 20.62523 0.68322 17.02941 0.56413 4.21702 0.31039 3.47887 0.25614 58100.256495 0.000347 0.18959 0.01504 0.97500 0 21.42653 0.66917 17.75046 0.55435 4.06220 0.29633 3.36304 0.24528 58100.257248 0.000405 0.20837 0.01500 0.99702 0 19.91022 0.59737 16.33365 0.49006 4.14864 0.27137 3.40384 0.22266 58100.315897 0.000292 0.22759 0.01818 1.00000 0 19.54853 0.67272 17.18455 0.59140 4.44909 0.32079 3.91343 0.28221 58100.316499 0.000310 0.20024 0.01583 1.00000 0 21.05269 0.68245 18.43438 0.59745 4.21556 0.30396 3.69398 0.26638 58100.317115 0.000307 0.21016 0.01646 1.00000 0 20.61561 0.68032 18.00131 0.59396 4.33258 0.30766 3.78176 0.26848 58100.318070 0.000648 0.19021 0.01107 0.99554 0 19.75714 0.45785 17.17650 0.39805 3.75794 0.20072 3.26820 0.17454
