/* ** ** 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 57140.242810 0.000298 0.15998 0.01231 0.99029 0 31.35085 0.89392 24.56468 0.69946 5.01554 0.35848 3.91278 0.27955 57140.243386 0.000278 0.16213 0.01310 1.00000 0 31.38909 0.93118 24.62995 0.72997 5.08910 0.38242 4.00641 0.30034 57140.244000 0.000336 0.13182 0.01020 1.00000 0 31.72760 0.83278 25.74295 0.67574 4.18228 0.30459 3.39442 0.24725 57140.244651 0.000315 0.13962 0.01063 0.99083 0 32.60134 0.87140 26.60548 0.71111 4.55165 0.32439 3.71395 0.26467 57140.245267 0.000301 0.14261 0.01078 1.00000 0 33.81675 0.90692 27.30522 0.73224 4.82262 0.34065 3.89321 0.27499 57140.245831 0.000263 0.16870 0.01312 0.97802 0 32.42122 0.94808 26.33000 0.76991 5.46960 0.39431 4.44176 0.32022 57140.246364 0.000269 0.15495 0.01197 0.98925 0 34.44903 0.96996 27.83105 0.78359 5.33783 0.38385 4.31869 0.31054 57140.246913 0.000281 0.15561 0.01222 1.00000 0 32.04018 0.92431 25.95681 0.74881 4.98580 0.36413 4.03865 0.29496 57140.247466 0.000272 0.17232 0.01352 0.97872 0 30.75512 0.92042 24.82442 0.74292 5.29964 0.38446 4.27753 0.31038 57140.248065 0.000327 0.13228 0.01031 1.00000 0 32.21867 0.85074 26.24359 0.69295 4.26174 0.31241 3.46875 0.25430 57140.248728 0.000336 0.13388 0.01035 1.00000 0 31.63594 0.84273 25.34780 0.67518 4.23554 0.30738 3.39253 0.24616 57140.249358 0.000295 0.15087 0.01174 0.99020 0 31.76461 0.89141 25.80702 0.72420 4.79231 0.34772 3.89637 0.28272 57140.249986 0.000333 0.13219 0.01052 1.00000 0 31.52806 0.84187 25.31449 0.67588 4.16762 0.31243 3.34448 0.25072 57140.250637 0.000318 0.13455 0.01046 1.00000 0 32.71932 0.87344 26.45531 0.70621 4.40239 0.32149 3.56136 0.26010 57140.251213 0.000258 0.16855 0.01316 1.00000 0 32.57581 0.96807 26.52585 0.78823 5.49066 0.39640 4.46674 0.32242 57140.251763 0.000292 0.14706 0.01135 1.00000 0 32.89724 0.90933 26.65290 0.73670 4.83796 0.34874 3.91402 0.28217 57140.252348 0.000292 0.15209 0.01163 1.00000 0 32.12547 0.89865 25.96737 0.72639 4.88583 0.34774 3.94934 0.28106 57140.252949 0.000310 0.14771 0.01117 0.98131 0 32.00166 0.87319 25.94839 0.70797 4.72694 0.33343 3.83496 0.27050 57140.253696 0.000437 0.15853 0.01004 0.98675 0 30.97036 0.72279 25.13614 0.58661 4.90960 0.28912 3.98716 0.23480
