From kawabata@subaru.naoj.org Mon Mar 04 12:07:18 2002 I02ddCAL.xy : Flux data (dd=08, 09, 10, 11; obs date) They are scaled as the flux at 5550A corresponds to the CCD photometry by Lew Cook (VSNET). http://www.astr.tohoku.ac.jp/~kawabata/sn2002/VMAGEST.jpg I have not corrected for strong atmospheric absorption around 6900 and 7600A due to O_2 and interstellar absorption such as Na D. qupt02dd.xy : Polarization data (dd=08, 09, 10) They include lambda(A), q(%), u(%), P(%), theta(deg), Perr. The data are binned to a constant photon noise of Perr = 0.05 %. I ignore the spectropolarimetric data on Feb. 11 because they had much lower S/N than those on other days. quptmean.xy : Polarization data averaged over above three days. In this period, no significant change was seen in polarization properties as seen in the above plot. Data format is same as above files. The data are binned to a constant photon noise of Perr = 0.02 %. I have not corrected for the heliocentric redshift in these data. ************************************************** Perr must stand for photon noise error.
