The Carnegie Supernova Project I: photometry data release of low-redshift stripped-envelope supernovae

Understand

The first phase of the Carnegie Supernova Project (CSP-I) was a dedicated supernova follow-up program based at the Las Campanas Observatory that collected science data of young, low-redshift supernovae between 2004 and 2009.

• Presented in this paper is the CSP-I photometric data release of low-redshift stripped-envelope core-collapse supernovae.
• The data consist of optical (uBgVri) photometry of 34 objects, with a subset of 26 having near-infrared (YJH) photometry.
• Twenty objects have optical pre-maximum coverage with a subset of 12 beginning at least five days prior to the epoch of B-band maximum brightness.
