/* ** ** 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 55631.342734 0.000408 0.07142 0.01046 0.99291 0 11.04112 0.41937 10.02071 0.38061 0.78856 0.11152 0.71548 0.10118 55631.343440 0.000298 0.10009 0.01486 0.98058 0 10.75985 0.48455 9.88474 0.44514 1.07690 0.15232 0.99175 0.14025 55631.344045 0.000307 0.09436 0.01370 0.99057 0 11.35107 0.48742 10.51464 0.45150 1.07105 0.14853 0.99213 0.13758 55631.344650 0.000298 0.09894 0.01485 1.00000 0 10.67004 0.48049 9.86890 0.44441 1.05567 0.15120 0.97606 0.13981 55631.345272 0.000324 0.08061 0.01212 0.99107 0 11.95405 0.48759 11.03247 0.45000 0.96363 0.13945 0.88766 0.12847 55631.346198 0.000602 0.09572 0.00988 0.99519 0 11.26555 0.34580 10.40040 0.31923 1.07837 0.10626 0.99683 0.09822 55631.347121 0.000321 0.09427 0.01412 0.99099 0 10.46808 0.45813 9.69400 0.42426 0.98685 0.14135 0.91394 0.13091 55631.348591 0.001149 0.10433 0.00785 0.97985 0 10.68547 0.24489 9.76985 0.22387 1.11485 0.07990 1.01930 0.07303 55631.350066 0.000327 0.09965 0.01425 1.00000 0 10.59871 0.45488 9.81525 0.42126 1.05619 0.14407 0.97835 0.13345 55631.350706 0.000312 0.08719 0.01287 0.99074 0 11.65466 0.49119 10.73363 0.45232 1.01621 0.14372 0.93614 0.13239 55631.351340 0.000321 0.08812 0.01287 0.97297 0 11.58984 0.48213 10.73565 0.44659 1.02130 0.14301 0.94602 0.13247 55631.351991 0.000330 0.08690 0.01283 0.99123 0 11.01279 0.46533 10.20079 0.43102 0.95700 0.13534 0.88643 0.12536 55631.352685 0.000365 0.09538 0.01291 0.99206 0 11.10067 0.44231 10.28076 0.40964 1.05878 0.13698 0.98059 0.12687 55631.353420 0.000370 0.07789 0.01170 0.99219 0 10.75517 0.43199 9.96111 0.40009 0.83768 0.12123 0.77585 0.11228 55631.354216 0.000425 0.06781 0.01013 0.97279 0 10.97007 0.40871 10.16193 0.37860 0.74384 0.10765 0.68905 0.09972 55631.355072 0.000431 0.09036 0.01181 0.97987 0 10.68580 0.39933 9.89802 0.36989 0.96561 0.12095 0.89443 0.11203
