/* ** ** 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 58521.251807 0.000446 0.12700 0.00982 1.00000 0 23.24425 0.59770 20.13684 0.51778 2.95197 0.21520 2.55576 0.18631 58521.252687 0.000434 0.13608 0.01039 0.98667 0 22.97541 0.60662 19.72101 0.52066 3.12647 0.22402 2.68266 0.19221 58521.253526 0.000405 0.13917 0.01065 1.00000 0 23.64206 0.63402 20.38362 0.54663 3.29031 0.23577 2.83595 0.20320 58521.254301 0.000370 0.15980 0.01246 0.95312 0 23.30272 0.66201 20.17903 0.57327 3.72368 0.27037 3.22459 0.23413 58521.255085 0.000414 0.15158 0.01170 0.98601 0 21.56046 0.60420 18.58618 0.52073 3.26819 0.23515 2.81716 0.20267 58521.255895 0.000396 0.15853 0.01217 0.99270 0 21.58359 0.61372 18.59561 0.52872 3.42174 0.24396 2.94882 0.21021 58521.256972 0.000680 0.14274 0.00848 0.98593 0 22.88299 0.48308 19.75402 0.41703 3.26637 0.18136 2.81956 0.15655 58521.321378 0.000434 0.15660 0.01225 0.98667 0 25.63770 0.72765 16.95620 0.48100 4.01496 0.29269 2.66005 0.19382 58521.322394 0.000582 0.12948 0.01005 0.99005 0 24.90153 0.65043 15.20833 0.39724 3.22433 0.23569 1.96826 0.14379 58521.323554 0.000579 0.12421 0.00962 0.99500 0 25.96286 0.65922 15.93567 0.40460 3.22491 0.23589 1.97937 0.14478 58521.324700 0.000567 0.13077 0.01018 0.98980 0 25.03622 0.65488 15.45837 0.40433 3.27397 0.24003 2.02005 0.14815 58521.325773 0.000506 0.15256 0.01167 0.98286 0 24.77933 0.69253 15.21589 0.42523 3.78044 0.26906 2.31901 0.16505 58521.326815 0.000535 0.14529 0.01134 0.98919 0 24.14902 0.66483 14.74374 0.40591 3.50859 0.25637 2.14035 0.15637 58521.327903 0.000553 0.15913 0.01198 0.97382 0 23.24665 0.64128 14.23706 0.39278 3.69926 0.25914 2.26627 0.15874
