/* ** ** 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 58205.228848 0.000567 0.13141 0.03057 0.97449 0 2.00085 0.16135 1.67479 0.13506 0.26293 0.05738 0.22026 0.04807 58205.230057 0.000642 0.10277 0.02416 0.98198 0 2.10618 0.15302 1.78749 0.12987 0.21646 0.04840 0.18379 0.04110 58205.231376 0.000677 0.11382 0.02688 0.97009 0 1.82427 0.13845 1.54965 0.11761 0.20764 0.04643 0.17651 0.03947 58205.232788 0.000735 0.09912 0.02325 0.98031 0 1.90960 0.13556 1.62366 0.11526 0.18928 0.04233 0.16091 0.03598 58205.233949 0.000425 0.15693 0.03787 0.97279 0 2.10139 0.19064 1.78481 0.16192 0.32977 0.07374 0.28019 0.06265 58205.234898 0.000524 0.14437 0.03458 0.94475 0 1.90790 0.16381 1.62353 0.13939 0.27544 0.06159 0.23431 0.05239 58205.235968 0.000547 0.13946 0.03390 0.98413 0 1.79511 0.15638 1.52412 0.13277 0.25034 0.05681 0.21261 0.04825 58205.237094 0.000579 0.13034 0.03103 0.97500 0 1.85681 0.15194 1.57693 0.12904 0.24201 0.05412 0.20547 0.04594 58205.238170 0.000498 0.15827 0.03816 0.98256 0 1.76405 0.15921 1.49845 0.13523 0.27920 0.06243 0.23708 0.05301 58205.239201 0.000532 0.13357 0.03182 0.97283 0 1.97436 0.16218 1.67572 0.13765 0.26371 0.05897 0.22384 0.05005 58205.240193 0.000460 0.15259 0.03714 0.96226 0 1.99319 0.17532 1.69399 0.14901 0.30413 0.06902 0.25847 0.05866 58205.241431 0.000778 0.09433 0.02208 0.96654 0 1.95220 0.13513 1.63717 0.11331 0.18415 0.04118 0.15410 0.03446 58205.242748 0.000538 0.11978 0.02879 0.98387 0 2.13056 0.16885 1.80323 0.14290 0.25521 0.05791 0.21610 0.04904 58205.243952 0.000666 0.10604 0.02497 0.96957 0 1.99752 0.14770 1.69396 0.12525 0.21181 0.04736 0.17967 0.04018 58205.245213 0.000596 0.15904 0.03274 0.99029 0 2.02717 0.15577 1.71350 0.13168 0.32240 0.06157 0.27241 0.05203
