摘要: We present near-infrared photometry of the Type Ia supernova (SN) 1999ee; also, optical and infrared SNe 2000bh, 2000ca, 2001ba. For 1999ee we first-ever SN at 1.035 μm (the Y band). K-corrections that transform in observer's frame to rest frame. Using our stretch factors derived from photometry, construct JHK templates can be used determine apparent magnitudes maximum if one has some data window -12 +10 days with respect T(Bmax). Following up previous work on uniformity V minus IR loci supernovae midrange decline rates, unreddened for slow decliners. also discuss evidence a continuous change color given epoch as function rate.
