/* ** ** 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 57182.481769 0.000587 0.16804 0.01312 1.00000 0 16.05574 0.47695 11.58512 0.34389 2.69804 0.19480 1.94661 0.14044 57182.482935 0.000579 0.17566 0.01374 0.98500 0 16.38409 0.49283 11.40939 0.34308 2.87808 0.20779 2.00590 0.14472 57182.484116 0.000602 0.17383 0.01354 0.97596 0 16.27761 0.48608 11.23891 0.33558 2.82959 0.20363 1.95648 0.14079 57182.485233 0.000515 0.18800 0.01491 0.99438 0 17.69615 0.55443 11.86640 0.37166 3.32685 0.24234 2.23446 0.16252 57182.486341 0.000593 0.16760 0.01290 0.97561 0 17.23577 0.50384 11.90233 0.34777 2.88870 0.20564 1.99416 0.14195 57182.487521 0.000587 0.17218 0.01349 0.97537 0 16.40029 0.48857 11.59455 0.34540 2.82383 0.20459 1.99662 0.14464 57182.488696 0.000587 0.16063 0.01253 0.98522 0 17.39651 0.50245 12.30861 0.35551 2.79434 0.20246 1.97665 0.14319 57182.489827 0.000544 0.17345 0.01403 0.98936 0 17.00019 0.51791 11.97348 0.36474 2.94870 0.22093 2.07610 0.15554 57182.491005 0.000634 0.17466 0.01296 0.97717 0 17.14097 0.48213 12.09634 0.34016 2.99376 0.20555 2.11260 0.14494
