OBJ: SN Ia 1991t in NGC 4527. DATE: January 11 1992: This is 276 days after the explosion assuming the rise time to the B maximum was 18 days. OBS: Gomez, Lopez, & Sanchez. REP: F_lambda (cgs) vs. lambda (ang) COR: dereshifted (heliocentric velocity 1732), not derreddened (foreground Galactic E(B-V)=0 and I estimated zero or small for the total in my 91t paper), photometric correction factors: No. t(days) U B V R I 1 276.0 .000E+00 4 1.539E-15 1 1.272E-15 0 1.452E-15 1 2.577E-15 1 I judge the V to be most trustworthy since that band is completely covered and has alot of flux. Also V band corrected this way gave a constant distance in Liu et al. 1997b. COMMENT: Obtained by scanning. Note I have used the cuta.f program to extract the normalized spectrum from the offset spectrum that G\'omez et al. present in their Fig.~12. REF: G\'omez, G., L\'opez, R., \&~S\'anchez, F. 1996, \aj, 112, 2094 Corrections: If the correction is the null case followed by what looks like the correction, then the correction has already been done and the second value is the correction factor that has been used. HELIO: 0. 1732. FCOR: 1.272E-15 A V band correction FECHO: 0. DAY: 276.
