dmag = SN - HHM 9 (V=12.56, B=13.61, Rc=12.04, Ic=11.61)
mag: calculated WITHOUT color correction
observer: T. Kato
telescope: 60-cm reflector at Ouda Station (Kyoto University)
* In calculating magnitudes, no color correction has been applied.
Because of large difference of colors between the SN and the comparison,
there exists fairly large systematic deviation from the standard system.
(Non-photometric condition has not allowed determination of the color
terms.)
* Galaxy background has been more explicitly removed assuming point
symmetry of the galaxy.
Result of re-analysis on Mar. 20 data are also given.
