/* ** ** 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 55574.473188 0.000327 0.08225 0.01972 0.96460 0 8.00666 0.52266 4.60716 0.29501 0.65858 0.15195 0.36282 0.08233 55574.473961 0.000446 0.07244 0.01707 0.96753 0 6.72947 0.41048 3.64357 0.22155 0.48746 0.11099 0.26542 0.06023 55574.474797 0.000391 0.09417 0.02204 0.96296 0 6.54754 0.45070 3.29576 0.22676 0.61659 0.13796 0.30821 0.06892 55574.475610 0.000422 0.09104 0.02160 0.96575 0 5.92618 0.40830 3.06687 0.21125 0.53951 0.12248 0.28048 0.06365 55574.476513 0.000480 0.07628 0.01770 0.93976 0 6.53653 0.40367 3.37186 0.20819 0.49858 0.11150 0.25684 0.05743 55574.477332 0.000339 0.11052 0.02612 0.98291 0 6.14149 0.46880 3.15242 0.24052 0.67875 0.15185 0.34841 0.07791 55574.478096 0.000425 0.08114 0.01945 1.00000 0 6.39617 0.42561 3.24330 0.21572 0.51899 0.11950 0.26550 0.06115 55574.479025 0.000503 0.06780 0.01591 0.97126 0 6.70396 0.39977 3.45290 0.20587 0.45452 0.10317 0.23401 0.05310 55574.479921 0.000394 0.08814 0.02058 0.98529 0 6.60989 0.44366 3.40252 0.22834 0.58262 0.13030 0.29901 0.06686 55574.480671 0.000356 0.10117 0.02265 0.94309 0 7.56959 0.50131 3.82790 0.25333 0.76580 0.16377 0.38826 0.08307 55574.481354 0.000327 0.12814 0.02946 0.98230 0 5.92476 0.46310 3.06323 0.23936 0.75920 0.16416 0.39238 0.08478 55574.482045 0.000353 0.10289 0.02420 0.98361 0 6.21110 0.45320 3.23854 0.23625 0.63909 0.14292 0.33389 0.07466 55574.482763 0.000365 0.10253 0.02254 0.96032 0 7.52161 0.50068 3.79559 0.25261 0.77119 0.16155 0.38878 0.08134 55574.483562 0.000434 0.07899 0.01836 0.96000 0 6.92986 0.43735 3.54515 0.22369 0.54741 0.12245 0.27824 0.06222 55574.484386 0.000391 0.10015 0.02383 0.95556 0 5.93601 0.42360 3.05498 0.21794 0.59446 0.13492 0.30657 0.06957 55574.485188 0.000411 0.08555 0.02026 0.95775 0 6.78868 0.44214 3.46436 0.22556 0.58077 0.13226 0.29789 0.06783 55574.485975 0.000376 0.09580 0.02308 0.96923 0 6.13643 0.43491 3.19286 0.22622 0.58785 0.13539 0.30975 0.07134 55574.486921 0.000570 0.06798 0.01500 0.97970 0 6.47801 0.36640 3.35174 0.18950 0.44039 0.09393 0.22836 0.04869
