Dataset
Data for: Inferring CSM Properties of Type II SNe Using a Magnitude-Limited ZTF Sample
16 Apr 2025
Abstract
Description
This data release contains the light curve models, raw forced photometry, and derived parameters for Type II SNe analysed in the paper "Inferring CSM Properties of Type II SNe Using a Magnitude-Limited ZTF Sample". The dataset includes photometric observations from the Zwicky Transient Facility (ZTF) Bright Transient Survey (BTS) and the resulting model fits with multi-output Gaussian Process regression used to infer circumstellar material (CSM) properties around Type II SN progenitors.
Contents
1. ZTF Forced Photometry
Raw forced photometry files for 493 Type II (incl. Type II, Type IIb and Type IIn) SNe from the ZTF Bright Transient Survey
Data format: Within Hinds_25_lcs, CSV files containing time series photometry in g, r, and i bands
Includes observation dates (MJD), flux, flux uncertainties, filter_ids and quality flags
Filenames follow the convention: [ZTFID]_BTS_fnu.csv
2. Light Curve Models
Best-fit light curve models in mag space for each supernova using CSM interaction models
Models generated using the methodology described in the associated paper
Data format: Within Hinds_25_lcs, CSV files containing light curve predictions
Filenames follow the convention: [ZTFID]_LC.csv
3. Parameter Table
Comprehensive table of derived parameters for all SNe in the sample
Includes physical parameters: rise time, absolute magnitude, CSM mass and CSM radius, among others
Data format: machine-readable table (produced with astropy)
Filename: Hinds_ea_25.dat
Methods
The photometric data were obtained through the ZTF forced photometry service, see A. A. Miller et al., (in prep.). Light curve modelling using multi-output Gaussian Processes. Full details of the methodology can be found in the associated paper.
