/* ** ** 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 57436.156915 0.000370 0.06684 0.01003 0.99219 0 13.71716 0.51160 11.58043 0.43182 0.91680 0.13327 0.77414 0.11249 57436.157655 0.000370 0.07200 0.01055 0.97656 0 13.42034 0.51526 11.10735 0.42643 0.96621 0.13665 0.80133 0.11333 57436.158344 0.000318 0.09196 0.01342 0.99091 0 12.92837 0.54966 10.60604 0.45093 1.18894 0.16591 0.97550 0.13612 57436.158969 0.000307 0.08274 0.01268 0.97170 0 13.93121 0.57646 11.54139 0.47746 1.15269 0.17010 0.95601 0.14120 57436.159611 0.000336 0.07337 0.01134 0.99138 0 13.95347 0.55282 11.42490 0.45272 1.02383 0.15290 0.83883 0.12526 57436.160288 0.000341 0.07763 0.01159 0.98305 0 13.64520 0.54492 11.14790 0.44517 1.05925 0.15233 0.86482 0.12436 57436.160986 0.000356 0.07258 0.01064 0.97561 0 14.04707 0.54277 11.50065 0.44438 1.01959 0.14419 0.83472 0.11805 57436.161721 0.000379 0.06517 0.00952 0.99237 0 14.33252 0.52733 11.80764 0.43441 0.93407 0.13211 0.77051 0.10897 57436.162652 0.000553 0.06874 0.00832 0.97771 0 13.90074 0.42802 11.39297 0.35080 0.95560 0.11185 0.78313 0.09166 57436.223737 0.000399 0.06292 0.00968 0.99275 0 12.47651 0.46141 11.17022 0.41310 0.78507 0.11720 0.70429 0.10513 57436.224585 0.000448 0.05457 0.00814 0.98710 0 13.29211 0.44782 11.77475 0.39667 0.72532 0.10544 0.64266 0.09336 57436.225346 0.000312 0.08627 0.01237 0.99074 0 12.98747 0.53473 11.45954 0.47178 1.12045 0.15392 0.99230 0.13630 57436.226017 0.000359 0.07312 0.01129 0.96774 0 12.39283 0.48407 10.96207 0.42817 0.90614 0.13538 0.80407 0.12002 57436.226697 0.000321 0.07948 0.01199 0.98198 0 12.78860 0.51897 11.34137 0.46022 1.01641 0.14774 0.90209 0.13105 57436.227340 0.000321 0.08085 0.01222 0.98198 0 12.55725 0.51861 11.16970 0.46127 1.01531 0.14757 0.90209 0.13105 57436.227967 0.000307 0.08613 0.01246 0.99057 0 12.95244 0.53289 11.53644 0.47459 1.11560 0.15471 0.99213 0.13758 57436.228720 0.000446 0.07597 0.01063 0.99351 0 12.13334 0.43046 10.73982 0.38099 0.92183 0.12470 0.81717 0.11050
