/* ** ** 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 55345.942324 0.000278 0.16532 0.01303 1.00000 0 27.19826 0.80299 24.70997 0.72949 4.49653 0.32852 4.07925 0.29812 55345.942894 0.000292 0.16519 0.01309 0.99010 0 25.51973 0.75099 23.60608 0.69468 4.21559 0.31012 3.89796 0.28677 55345.943452 0.000266 0.17947 0.01415 1.00000 0 25.75547 0.79154 23.82734 0.73228 4.62235 0.33558 4.27630 0.31046 55345.944011 0.000292 0.16713 0.01299 1.00000 0 25.56092 0.75285 23.50208 0.69219 4.27209 0.30730 3.93302 0.28292 55345.944618 0.000315 0.16351 0.01263 0.98165 0 25.08795 0.71790 22.84496 0.65369 4.10216 0.29432 3.73120 0.26771 55345.945223 0.000289 0.17051 0.01322 0.98000 0 25.98260 0.76724 23.78963 0.70242 4.43030 0.31749 4.05147 0.29028 55345.945761 0.000249 0.19896 0.01582 1.00000 0 25.10913 0.81594 22.99418 0.74713 4.99569 0.36268 4.57465 0.33212 55345.946302 0.000292 0.17680 0.01371 0.99010 0 24.43791 0.73696 22.56818 0.68057 4.32069 0.30877 3.99047 0.28518 55345.946896 0.000301 0.15404 0.01258 1.00000 0 25.79398 0.74411 23.77060 0.68568 3.97326 0.30360 3.66278 0.27969 55345.947486 0.000289 0.17406 0.01374 1.00000 0 24.43884 0.74002 22.61402 0.68476 4.25373 0.31005 3.93612 0.28690 55345.948114 0.000339 0.14729 0.01108 0.99145 0 25.72321 0.69849 23.80245 0.64634 3.78874 0.26592 3.50584 0.24606 55345.948736 0.000284 0.17353 0.01348 1.00000 0 25.40368 0.76226 23.36153 0.70093 4.40837 0.31583 4.05147 0.29028 55345.949326 0.000307 0.15521 0.01218 1.00000 0 25.86365 0.73841 23.79481 0.67935 4.01426 0.29336 3.69442 0.27000 55345.949942 0.000310 0.15903 0.01242 1.00000 0 25.09722 0.72176 23.10952 0.66459 3.99124 0.28973 3.67682 0.26694 55345.950562 0.000310 0.15544 0.01227 0.99065 0 25.59402 0.73371 23.66219 0.67832 3.97839 0.29267 3.67732 0.27054 55345.951181 0.000310 0.15194 0.01167 0.98131 0 26.89771 0.74557 24.88787 0.68986 4.08673 0.29280 3.78137 0.27092 55345.951803 0.000312 0.16630 0.01289 0.97222 0 24.58565 0.71079 22.74913 0.65770 4.08860 0.29411 3.78319 0.27214 55345.952474 0.000359 0.13085 0.01028 0.99194 0 26.05254 0.68151 24.10603 0.63059 3.40906 0.25247 3.15435 0.23361 55345.953146 0.000312 0.14999 0.01153 1.00000 0 26.49745 0.73719 24.50728 0.68182 3.97446 0.28476 3.67633 0.26340 55345.953736 0.000278 0.17919 0.01398 0.98958 0 25.36163 0.76803 23.32011 0.70616 4.54458 0.32688 4.18142 0.30079 55345.954367 0.000353 0.13917 0.01084 0.99180 0 25.24459 0.68123 23.24070 0.62712 3.51328 0.25683 3.23643 0.23653 55345.955119 0.000399 0.14859 0.01028 0.98551 0 26.06302 0.64726 24.10627 0.59866 3.87281 0.25011 3.58231 0.23134
