/* ** ** 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 54978.712329 0.000292 0.16375 0.01258 1.00000 0 27.13444 0.78290 24.13604 0.69632 4.44323 0.31623 3.94902 0.28109 54978.712908 0.000286 0.16569 0.01282 0.98990 0 27.23627 0.79489 24.45325 0.71363 4.51283 0.32332 4.05137 0.29028 54978.713469 0.000275 0.17247 0.01380 0.98947 0 26.57888 0.80125 23.91672 0.72106 4.58399 0.33973 4.12716 0.30570 54978.714039 0.000295 0.16976 0.01333 0.99020 0 25.44397 0.75320 23.07236 0.68299 4.31946 0.31404 3.91676 0.28476 54978.714606 0.000272 0.17154 0.01345 1.00000 0 27.37321 0.82125 24.47948 0.73440 4.69567 0.34006 4.20644 0.30461 54978.715156 0.000278 0.16938 0.01349 0.98958 0 26.71803 0.79637 24.23630 0.72239 4.52542 0.33430 4.10481 0.30322 54978.715720 0.000286 0.16484 0.01262 0.98990 0 27.76940 0.80172 25.04989 0.72312 4.57762 0.32466 4.13314 0.29315 54978.716296 0.000289 0.16250 0.01263 0.99000 0 27.33014 0.79216 24.57238 0.71214 4.44103 0.32030 3.99210 0.28793 54978.716898 0.000312 0.14433 0.01120 1.00000 0 28.14044 0.77374 25.24579 0.69409 4.06142 0.29482 3.64261 0.26448 54978.717456 0.000246 0.18398 0.01446 1.00000 0 28.45001 0.88742 25.27481 0.78833 5.23418 0.37755 4.64963 0.33536 54978.718021 0.000318 0.14456 0.01119 1.00000 0 27.79204 0.76257 24.85436 0.68189 4.01749 0.29090 3.59460 0.26030 54978.718640 0.000301 0.15327 0.01174 1.00000 0 27.71430 0.78218 25.00632 0.70579 4.24766 0.30237 3.83510 0.27298 54978.719224 0.000284 0.16870 0.01300 0.98980 0 27.15035 0.79359 24.49109 0.71586 4.58033 0.32650 4.13445 0.29473 54978.719809 0.000301 0.16173 0.01264 0.99038 0 26.17156 0.75633 23.58958 0.68169 4.23279 0.30735 3.81944 0.27731 54978.720385 0.000275 0.17324 0.01357 1.00000 0 26.66449 0.79832 24.03264 0.71950 4.61946 0.33446 4.16216 0.30141 54978.720946 0.000286 0.15655 0.01208 1.00000 0 28.53406 0.81073 25.73919 0.73132 4.46701 0.32055 4.03258 0.28935 54978.721545 0.000312 0.14511 0.01144 1.00000 0 27.42414 0.75762 24.88306 0.68742 3.97953 0.29396 3.61071 0.26672 54978.722158 0.000301 0.15581 0.01200 1.00000 0 27.30270 0.77306 24.50009 0.69361 4.25395 0.30482 3.81764 0.27353 54978.722740 0.000281 0.16383 0.01291 1.00000 0 27.21105 0.79934 24.64967 0.72400 4.45802 0.32588 4.03697 0.29506 54978.723290 0.000269 0.18385 0.01445 1.00000 0 25.54926 0.79672 23.12258 0.72104 4.69723 0.33881 4.24966 0.30651 54978.723929 0.000370 0.15838 0.01073 1.00000 0 27.65856 0.69908 25.01993 0.63232 4.38056 0.27542 3.95972 0.24895
