/* ** ** 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 57194.927422 0.000373 0.11856 0.01604 0.96899 0 9.29016 0.40383 8.31747 0.36153 1.10140 0.14110 0.98658 0.12639 57194.928146 0.000350 0.09824 0.01502 0.98347 0 9.31023 0.41823 8.33638 0.37448 0.91464 0.13363 0.81943 0.11973 57194.928837 0.000341 0.10329 0.01551 0.99153 0 9.21970 0.42477 8.20612 0.37807 0.95232 0.13614 0.84856 0.12131 57194.929485 0.000307 0.11214 0.01706 0.97170 0 9.57497 0.45374 8.61593 0.40829 1.07372 0.15524 0.96617 0.13969 57194.930232 0.000440 0.07779 0.01166 0.98684 0 9.37101 0.37356 8.43236 0.33615 0.72900 0.10536 0.65598 0.09481 57194.931010 0.000339 0.10474 0.01572 0.96581 0 9.37400 0.42770 8.39372 0.38297 0.98184 0.14036 0.87860 0.12560 57194.931664 0.000315 0.11010 0.01640 0.97248 0 9.53840 0.44708 8.58281 0.40229 1.05018 0.14852 0.94497 0.13364 57194.932306 0.000327 0.11485 0.01733 0.99115 0 8.57313 0.41299 7.71925 0.37186 0.98462 0.14076 0.88645 0.12673 57194.933018 0.000385 0.09768 0.01479 0.99248 0 8.47647 0.38162 7.63141 0.34358 0.82796 0.11966 0.74543 0.10773 57194.933773 0.000370 0.09748 0.01474 0.97656 0 8.97368 0.39834 8.07499 0.35845 0.87478 0.12643 0.78718 0.11377 57194.934543 0.000399 0.09525 0.01408 0.95652 0 8.85395 0.38242 7.96680 0.34410 0.84334 0.11927 0.75884 0.10732 57194.935295 0.000353 0.11277 0.01679 0.94262 0 8.57987 0.39991 7.72498 0.36006 0.96754 0.13683 0.87102 0.12318 57194.936051 0.000402 0.08540 0.01298 0.98561 0 9.26086 0.38884 8.33477 0.34996 0.79090 0.11557 0.71177 0.10400 57194.936823 0.000370 0.10735 0.01596 0.96094 0 8.43063 0.38622 7.58599 0.34752 0.90504 0.12799 0.81436 0.11517 57194.937564 0.000365 0.09938 0.01473 0.96825 0 9.28099 0.40858 8.35320 0.36773 0.92234 0.13053 0.83021 0.11749 57194.938241 0.000312 0.11379 0.01751 0.98148 0 9.03783 0.43600 8.09260 0.39040 1.02844 0.15025 0.91993 0.13442 57194.939048 0.000495 0.11361 0.01368 1.00000 0 9.17437 0.34980 8.22468 0.31359 1.04228 0.11902 0.93479 0.10672
