/* ** ** 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 60023.008298 0.000460 0.11752 0.00897 0.98742 0 24.80356 0.60784 21.50907 0.52692 2.91492 0.21072 2.53102 0.18284 60023.009227 0.000469 0.11424 0.00871 1.00000 0 24.27281 0.60112 21.35981 0.52897 2.77301 0.20004 2.43944 0.17597 60023.010115 0.000420 0.12098 0.00932 0.98621 0 25.80227 0.64218 22.74706 0.56613 3.12168 0.22761 2.75203 0.20066 60023.011015 0.000480 0.10940 0.00858 0.98795 0 24.38108 0.59000 21.51901 0.52061 2.66722 0.19902 2.35402 0.17560 60023.011898 0.000402 0.12877 0.00975 0.99281 0 25.45176 0.65662 22.44753 0.57915 3.27732 0.23329 2.89015 0.20573 60023.012812 0.000512 0.10068 0.00767 0.99435 0 25.11563 0.57936 22.19282 0.51195 2.52876 0.18366 2.23502 0.16231 60023.013721 0.000396 0.12181 0.00940 1.00000 0 26.73915 0.67824 23.59042 0.59840 3.25715 0.23744 2.87256 0.20945 60023.014540 0.000422 0.12551 0.00946 0.99315 0 24.93375 0.63157 22.00588 0.55739 3.12945 0.22226 2.76444 0.19628 60023.015399 0.000437 0.11335 0.00885 1.00000 0 25.81425 0.63549 22.67078 0.55811 2.92610 0.21676 2.56877 0.19033 60023.016232 0.000396 0.13644 0.01042 0.97810 0 24.50374 0.64720 21.71445 0.57353 3.34328 0.23957 2.96280 0.21231 60023.017095 0.000466 0.11349 0.00889 0.97516 0 24.76383 0.60495 21.79518 0.53241 2.81036 0.20911 2.47173 0.18387 60023.018000 0.000440 0.12176 0.00929 1.00000 0 24.43920 0.61827 21.48096 0.54340 2.97578 0.21412 2.61311 0.18801 60023.019259 0.000819 0.10930 0.00635 0.98940 0 25.27685 0.45578 22.36919 0.40335 2.76279 0.15250 2.44484 0.13493
