/* ** ** 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 60056.887226 0.000168 0.21691 0.01720 0.98276 0 44.14626 1.46091 32.26296 1.06737 9.57566 0.69009 7.00663 0.50483 60056.887544 0.000150 0.22728 0.01839 1.00000 0 45.46235 1.59572 33.26606 1.16752 10.33257 0.75341 7.56821 0.55180 60056.887885 0.000191 0.19671 0.01562 0.98485 0 43.13591 1.38322 30.70486 0.98462 8.48546 0.61628 6.05181 0.43947 60056.888267 0.000191 0.24214 0.01960 1.00000 0 36.67759 1.32558 24.81486 0.89692 8.88101 0.64326 5.99047 0.43387 60056.888632 0.000174 0.22620 0.01848 0.98333 0 43.16824 1.49340 29.42540 1.01747 9.76451 0.72265 6.64543 0.49162 60056.889014 0.000208 0.21584 0.01743 0.98611 0 38.28551 1.30369 25.48298 0.86734 8.26352 0.60528 5.51470 0.40315 60056.889410 0.000188 0.23087 0.01888 1.00000 0 38.98098 1.38740 25.95384 0.92376 8.99968 0.66241 5.99568 0.44126 60056.889948 0.000350 0.24473 0.01437 0.99467 0 37.35534 0.97020 25.79545 0.66981 9.14205 0.48141 6.30819 0.33212 60056.934125 0.000532 0.23570 0.00843 0.98913 0 50.29433 0.78260 46.28924 0.72024 11.85445 0.38154 10.90832 0.35109 60056.935199 0.000541 0.22729 0.00808 1.00000 0 50.31321 0.77340 46.69080 0.71772 11.43551 0.36670 10.61234 0.34031 60056.935882 0.000142 0.20145 0.01485 1.00000 0 51.34585 1.53002 47.65436 1.42002 10.34345 0.69739 9.59981 0.64725 60056.936547 0.000524 0.24422 0.00878 1.00000 0 48.24519 0.76781 44.77686 0.71262 11.78242 0.37982 10.93538 0.35251 60056.937291 0.000220 0.20921 0.01227 0.98825 0 49.64607 1.22647 46.07707 1.13830 10.38638 0.55230 9.63972 0.51259
