/* ** ** Swift/XRT hardness ratio for PKS 2155-304. ** 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 57238.253185 0.000680 0.17862 0.02768 0.95319 0 3.09207 0.18611 2.48573 0.14958 0.55231 0.07886 0.44341 0.06330 57238.254307 0.000443 0.11215 0.02669 0.90850 0 3.15639 0.23280 2.53626 0.18706 0.35399 0.08010 0.28521 0.06453 57238.255054 0.000304 0.14401 0.03481 0.96190 0 3.39281 0.28898 2.72501 0.23210 0.48861 0.11053 0.39252 0.08880 57238.255682 0.000324 0.14442 0.03485 0.92857 0 3.24781 0.27228 2.62829 0.22033 0.46904 0.10614 0.38120 0.08624 57238.256324 0.000318 0.13869 0.03345 0.95455 0 3.32513 0.27777 2.72070 0.22728 0.46116 0.10433 0.37757 0.08542 57238.256955 0.000312 0.14207 0.03317 0.98148 0 3.41474 0.28321 2.79510 0.23181 0.48515 0.10587 0.39689 0.08661 57238.257571 0.000304 0.13449 0.03241 0.98095 0 3.50791 0.29147 2.86116 0.23773 0.47179 0.10673 0.38490 0.08708 57238.258286 0.000411 0.12139 0.02939 0.95775 0 2.91801 0.22982 2.36243 0.18606 0.35423 0.08108 0.28840 0.06602 57238.258998 0.000301 0.15653 0.03807 0.97115 0 3.07275 0.27417 2.50651 0.22365 0.48098 0.10882 0.39252 0.08880 57238.259814 0.000515 0.09528 0.02230 0.97191 0 2.97631 0.20588 2.42990 0.16808 0.28357 0.06341 0.23160 0.05179 57238.260653 0.000324 0.13760 0.03360 0.99107 0 3.16622 0.26843 2.57599 0.21838 0.43566 0.09977 0.35336 0.08089 57238.261312 0.000336 0.17086 0.03939 0.95690 0 2.84619 0.24979 2.32149 0.20373 0.48631 0.10368 0.39706 0.08465 57238.261972 0.000324 0.13488 0.03255 0.99107 0 3.26292 0.27362 2.64176 0.22152 0.44009 0.09957 0.35716 0.08080 57238.262915 0.000619 0.15263 0.02599 0.96262 0 3.15678 0.19354 2.57420 0.15781 0.48183 0.07656 0.39258 0.06237 57238.263850 0.000315 0.15374 0.03642 0.97248 0 3.12336 0.26905 2.55614 0.22019 0.48019 0.10596 0.39291 0.08670 57238.264510 0.000344 0.14050 0.03374 0.97479 0 3.00823 0.26308 2.45070 0.21422 0.42267 0.09451 0.34540 0.07723 57238.265305 0.000451 0.09384 0.02245 0.97436 0 3.35980 0.23331 2.74829 0.19085 0.31528 0.07218 0.25804 0.05907 57238.266260 0.000503 0.09317 0.02206 0.98851 0 3.02515 0.21133 2.47654 0.17300 0.28185 0.06376 0.23049 0.05215 57238.267241 0.000477 0.07849 0.01844 0.96364 0 3.88258 0.24541 3.17907 0.20094 0.30474 0.06894 0.24934 0.05641 57238.268115 0.000396 0.11017 0.02596 0.96350 0 3.36590 0.25018 2.75477 0.20476 0.37083 0.08292 0.30354 0.06787 57238.268977 0.000466 0.11721 0.02579 0.96273 0 3.17851 0.22651 2.59761 0.18511 0.37257 0.07756 0.30475 0.06344
