VizieR Online Data Catalog: CNIa0.02 project DR1: type Ia SN z<0.02 light curves (Chen+, 2022)
Abstract
We select our targets primarily based on ASAS-SN detections, and the complete sample was collected between 2015 September 17 and 2019 January 31. We have also observed a few SNe Ia before (since 2015 January) and after this period (until 2020 January), and they are included in DR1, but are not part of the complete sample.
CNIa0.02 DR1 includes V-band and g-band photometry from the 14cm telescopes used to conduct the ASAS-SN survey. Immediately after the discovery of an SN candidate that met our magnitude criteria, we started multiband photometric observations. For most objects, this data release contains follow-up photometry ending around 40-60days after the optical peak. We have performed photometric follow-up observations using a number of telescopes ranging from ~0.3m to ~2m (see Table 3; Section 2 and Appendix B). (5 data files).- Publication:
