/* ** ** 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 57723.248433 0.000414 0.12469 0.01894 0.96503 0 6.35100 0.31860 5.77130 0.28953 0.79193 0.11354 0.71818 0.10294 57723.249144 0.000298 0.06456 0.01490 0.98058 0 6.73009 0.38344 6.14419 0.35006 0.43448 0.09715 0.39670 0.08870 57723.249986 0.000538 0.09223 0.01400 0.99462 0 6.38561 0.28073 5.75549 0.25304 0.58893 0.08560 0.53001 0.07700 57723.250985 0.000454 0.10490 0.01620 0.98089 0 6.65521 0.30981 5.99970 0.27929 0.69814 0.10281 0.62983 0.09275 57723.251731 0.000292 0.06358 0.01467 1.00000 0 6.83648 0.38994 6.23759 0.35578 0.43468 0.09720 0.39670 0.08870 57723.252541 0.000518 0.10132 0.01504 0.97765 0 6.24377 0.28231 5.64402 0.25519 0.63259 0.08947 0.57238 0.08095 57723.253618 0.000558 0.08563 0.01261 0.97409 0 6.84436 0.28170 6.22678 0.25627 0.58610 0.08289 0.53280 0.07535 57723.254628 0.000451 0.10663 0.01587 0.98077 0 6.75684 0.31387 6.14259 0.28532 0.72050 0.10190 0.65468 0.09259 57723.255663 0.000584 0.08181 0.01204 0.98020 0 6.79922 0.27702 6.18395 0.25195 0.55621 0.07866 0.50589 0.07154 57723.256737 0.000489 0.09767 0.01449 1.00000 0 6.68919 0.30050 6.06992 0.27264 0.65334 0.09240 0.59270 0.08382 57723.257628 0.000402 0.11993 0.01794 0.96403 0 6.82752 0.33350 6.23298 0.30446 0.81882 0.11580 0.74751 0.10571 57723.258869 0.000833 0.11949 0.01317 0.99653 0 6.03247 0.21907 5.48433 0.19917 0.72080 0.07500 0.65575 0.06823
