Carnegie Supernova Project Data for UDT

CONTENTS:--------- 1. PHOTOMETRY (134 Type Ia SNe) - Location: /photometry/ - Format: SNooPy-compatible text files - Coverage: 2004-2010 (CSP-I DR3) - Filters: ugri, BV, YJH - Redshift range: 0.0079 < z < 0.0797 2. METADATA - Location: /metadata/ - tab1.dat: Host galaxies, morphologies, redshifts - README: Original CSP documentation - SN_photo.dat: Concatenated photometry tables - 2003fg-like SNe properties (Ashall+ 2021) 3. FILTER CALIBRATIONS - Location: /filters/ - Complete transmission curves for all CSP filters - Includes atmospheric correction - Multiple V filter versions (time-dependent) 4. BOLOMETRIC DATA - Location: /bolometric/ - Quasi-bolometric light curves (33 SNe) - K-corrections applied 5. VELOCITY DATA - Location: /velocity/ - Si II λ6355 velocity evolution (33 SNe) 6. SPECTRA - Location: /spectra/ - Optical and NIR spectra for select objects - Includes 2003fg-like SNe spectra DATA QUALITY:-------------- Photometric precision: 0.01-0.03 mag (optical)- NIR precision: 0.02-0.05 mag- Well-characterized systematics- Independent calibration from Pantheon+/DES HOST GALAXY MASSES:-------------------- Not included in CSP DR3- Searched for but not available in standard release- 2003fg-like SNe file has some host properties but no masses- Would need literature cross-matching for stellar masses
