Improved Distances to Type Ia Supernovae with Multicolor Light Curve Shapes: MLCS2k2


We present an updated version of the Multicolor Light Curve Shape method to measure distances to type Ia supernovae (SN Ia), incorporating new procedures for Kcorrection and extinction corrections. We also develop a simple model to disentangle intrinsic color variations and reddening by dust, and expand the method to incorporate U-band light curves and to… (More)
