Lick Observatory Supernova Search Follow-Up Program: Photometry Data
  Release of 93 Type Ia Supernovae
  We present BVRI and unfiltered light curves of 93 Type Ia supernovae (SNe Ia)
from the Lick Observatory Supernova Search (LOSS) follow-up program conducted
between 2005 and 2018. Our sample consists of 78 spectroscopically normal SNe
Ia, with the remainder divided between distinct subclasses (three SN
1991bg-like, three SN 1991T-like, four SNe Iax, two peculiar, and three
super-Chandrasekhar events), and has a median redshift of 0.0192. The SNe in
our sample have a median coverage of 16 photometric epochs at a cadence of 5.4
days, and the median first observed epoch is ~4.6 days before maximum B-band
light. We describe how the SNe in our sample are discovered, observed, and
processed, and we compare the results from our newly developed automated
photometry pipeline to those from the previous processing pipeline used by
LOSS. After investigating potential biases, we derive a final systematic
uncertainty of 0.03 mag in BVRI for our dataset. We perform an analysis of our
light curves with particular focus on using template fitting to measure the
parameters that are useful in standardising SNe Ia as distance indicators. All
of the data are available to the community, and we encourage future studies to
incorporate our light curves in their analyses.
