1999A&A...349..877D

object{SN 1994D} of type Ia has been suspected not to fit into the relation between decline rate, colour, and brightness. However, an individual distance of its host galaxy, NGC 4526, other than that of the Virgo cluster, has not yet been published. We determined the distance by the method of globular cluster luminosity functions on the basis of HST archive data. A maximum-likelihood fit returns apparent turn-over magnitudes of 23.16±0.16mag in V and 21.96±0.09mag in I. The corresponding distance modulus is 30.4±0.3mag, where the error reflects our estimation of the absolute distance scale. The absolute magnitudes (not corrected for decline rate and colour) are -18.67±0.30mag, -18.62±0.30mag, and -18.40±0.30mag for B, V, and I, respectively. The corrected magnitudes are -18.69±0.31mag, -18.69±0.31mag, and -18.44±0.31mag. Compared with other supernovae with reliably determined distances, SN 1994D fits within the errors. It is therefore not a counter-example against a uniform decline-rate-colour-brightness relation.
