/* ** ** 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 57475.078816 0.000408 0.10702 0.02522 0.95745 0 3.29465 0.24493 2.75935 0.20513 0.35260 0.07885 0.29679 0.06636 57475.079565 0.000341 0.11594 0.02741 0.97458 0 3.58845 0.27556 3.01646 0.23159 0.41606 0.09304 0.34841 0.07791 57475.080641 0.000735 0.13619 0.02066 0.96063 0 3.55642 0.18714 3.00336 0.15804 0.48436 0.06890 0.40840 0.05809 57475.081755 0.000379 0.09927 0.02329 0.99237 0 3.66311 0.26074 3.10490 0.22101 0.36363 0.08131 0.30821 0.06892 57475.082438 0.000304 0.14633 0.03708 0.96190 0 3.03317 0.26903 2.57094 0.22803 0.44384 0.10535 0.37620 0.08929 57475.083049 0.000307 0.12974 0.03130 0.97170 0 3.49145 0.28635 2.95945 0.24272 0.45299 0.10279 0.38397 0.08713 57475.083755 0.000399 0.09541 0.02237 0.99275 0 3.61573 0.25434 3.06526 0.21562 0.34498 0.07714 0.29246 0.06540 57475.084776 0.000622 0.17725 0.02579 0.97674 0 3.59248 0.20479 3.03445 0.17297 0.63678 0.08522 0.53883 0.07211
