/* ** ** 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 59918.490093 0.000197 0.17479 0.01353 1.00000 0 39.66108 1.19629 33.72445 1.01749 6.93235 0.49412 5.89789 0.42040 59918.490457 0.000168 0.18204 0.01425 1.00000 0 43.16195 1.33018 37.60549 1.15884 7.85737 0.56533 6.84905 0.49266 59918.490816 0.000191 0.16439 0.01292 1.00000 0 41.64211 1.22511 36.28391 1.06747 6.84562 0.49891 5.96406 0.43468 59918.491186 0.000179 0.17850 0.01404 1.00000 0 41.85770 1.28563 35.75306 1.09804 7.47156 0.54100 6.37800 0.46180 59918.491551 0.000185 0.17522 0.01369 1.00000 0 41.56927 1.26629 35.42847 1.07926 7.28391 0.52392 6.20695 0.44647 59918.491916 0.000179 0.18286 0.01435 1.00000 0 41.04715 1.27037 34.84398 1.07836 7.50593 0.54144 6.37486 0.45974 59918.492283 0.000188 0.17031 0.01317 0.98462 0 43.16901 1.27442 36.60043 1.08053 7.35225 0.52548 6.23521 0.44558 59918.492665 0.000194 0.16426 0.01277 1.00000 0 42.05242 1.23767 36.05835 1.06120 6.90761 0.49690 5.92903 0.42648 59918.493044 0.000185 0.17312 0.01399 1.00000 0 40.61595 1.23654 34.85079 1.06094 7.03133 0.52617 6.03740 0.45181 59918.493412 0.000182 0.16939 0.01312 1.00000 0 44.58702 1.32246 37.59664 1.11513 7.55253 0.54047 6.36907 0.45579 59918.493756 0.000162 0.19883 0.01553 1.00000 0 42.37727 1.36401 36.42580 1.17245 8.42607 0.59986 7.23675 0.51525 59918.494115 0.000197 0.16458 0.01266 1.00000 0 42.47547 1.23461 36.19625 1.05207 6.99064 0.49773 5.95968 0.42432 59918.494471 0.000159 0.20603 0.01623 1.00000 0 41.35406 1.35640 35.05373 1.14966 8.52026 0.61041 7.21909 0.51721 59918.494824 0.000194 0.16902 0.01316 1.00000 0 40.99461 1.21974 35.10558 1.04446 6.92881 0.49860 5.92903 0.42648 59918.495197 0.000179 0.19847 0.01549 0.98387 0 38.39398 1.22664 32.95195 1.05268 7.62011 0.54240 6.53866 0.46540 59918.495561 0.000185 0.17285 0.01338 0.98438 0 42.39650 1.26363 36.65008 1.09235 7.32807 0.52368 6.33418 0.45265 59918.495958 0.000211 0.15222 0.01194 1.00000 0 41.11920 1.17186 35.28483 1.00550 6.25897 0.45728 5.36472 0.39204 59918.496340 0.000171 0.18306 0.01422 1.00000 0 42.70396 1.32987 36.93170 1.15011 7.81741 0.55641 6.76031 0.48117 59918.496693 0.000182 0.18493 0.01452 0.98413 0 39.93071 1.23928 34.46553 1.06964 7.38451 0.53255 6.37486 0.45974 59918.497049 0.000174 0.18517 0.01454 1.00000 0 41.96739 1.30495 35.57712 1.10628 7.77102 0.56050 6.58736 0.47507 59918.497390 0.000168 0.18802 0.01526 1.00000 0 41.80552 1.33598 35.63975 1.13893 7.86045 0.58628 6.69650 0.49974 59918.497740 0.000182 0.17923 0.01447 1.00000 0 39.70726 1.23107 34.22050 1.06087 7.11685 0.53061 6.13014 0.45698 59918.498102 0.000179 0.17553 0.01364 1.00000 0 43.00489 1.30079 36.83683 1.11412 7.54864 0.54032 6.47180 0.46314 59918.498475 0.000194 0.16512 0.01315 1.00000 0 40.76203 1.21798 35.25356 1.05339 6.73065 0.49707 5.82105 0.42989 59918.498987 0.000318 0.19256 0.01121 1.00000 0 40.21624 0.94744 34.21292 0.80604 7.74410 0.41223 6.58344 0.35035
