/* ** ** 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 57505.027110 0.000272 0.18190 0.01433 1.00000 0 25.56383 0.78335 23.01678 0.70528 4.65014 0.33740 4.18652 0.30378 57505.027642 0.000260 0.18155 0.01467 1.00000 0 26.35437 0.82567 23.63677 0.74044 4.78468 0.35637 4.29332 0.31974 57505.028184 0.000281 0.16850 0.01299 1.00000 0 27.25588 0.80766 24.41742 0.72351 4.59263 0.32684 4.11220 0.29265 57505.028710 0.000246 0.18601 0.01454 1.00000 0 28.43246 0.88293 25.24266 0.78388 5.28869 0.37924 4.69792 0.33694 57505.029190 0.000234 0.20498 0.01598 1.00000 0 27.63454 0.89941 24.25654 0.78946 5.66460 0.40113 4.97395 0.35220 57505.029679 0.000255 0.19104 0.01530 0.98864 0 26.53320 0.84308 23.48681 0.74625 5.06903 0.37257 4.48237 0.32950 57505.030203 0.000269 0.17316 0.01334 0.97849 0 28.46750 0.83745 25.31256 0.74457 4.92937 0.35089 4.38334 0.31195 57505.030721 0.000249 0.19487 0.01522 0.98837 0 27.16761 0.85828 24.12078 0.76200 5.29409 0.37819 4.69533 0.33546 57505.031233 0.000263 0.18096 0.01402 1.00000 0 27.66659 0.84579 24.22271 0.74051 5.00644 0.35630 4.38334 0.31195 57505.031751 0.000255 0.19222 0.01521 0.98864 0 26.87078 0.84674 23.53315 0.74157 5.16498 0.37478 4.52337 0.32822 57505.032284 0.000278 0.16922 0.01312 1.00000 0 27.90706 0.82618 24.44506 0.72369 4.72255 0.33827 4.13646 0.29629 57505.032833 0.000272 0.17127 0.01337 1.00000 0 27.83794 0.83224 24.56620 0.73440 4.76776 0.34370 4.20550 0.30318 57505.033369 0.000263 0.18508 0.01443 0.98901 0 27.12640 0.83317 23.85679 0.73272 5.02061 0.35965 4.41222 0.31604 57505.033884 0.000252 0.20138 0.01576 0.97701 0 26.44241 0.84581 23.30709 0.74546 5.32486 0.38039 4.69533 0.33546 57505.034387 0.000252 0.17636 0.01388 1.00000 0 29.08505 0.88442 25.65473 0.78011 5.12940 0.37226 4.52337 0.32822 57505.034923 0.000284 0.15780 0.01243 1.00000 0 28.96339 0.83299 25.34544 0.72894 4.57039 0.33506 3.99969 0.29323 57505.035481 0.000275 0.17481 0.01350 1.00000 0 27.25381 0.81774 24.02079 0.72082 4.76417 0.33903 4.19877 0.29882 57505.036037 0.000281 0.16200 0.01267 1.00000 0 28.60715 0.83672 25.04347 0.73248 4.63429 0.33627 4.05704 0.29438 57505.036609 0.000292 0.16671 0.01284 0.99010 0 27.15695 0.79139 24.05077 0.70091 4.52736 0.32268 4.01107 0.28584 57505.037188 0.000286 0.17590 0.01373 1.00000 0 26.59484 0.79035 23.55589 0.69998 4.67815 0.33761 4.14585 0.29901
