Up to date epochs for SV Eri and DX Del
Dear Forum members,
I am doing a Master's thesis project at Lund Observatory, Sweden, on RR Lyrae variables. For this I need up to date epochs for SV Eri and DX Del. I tried using the VSX of AAVSO, but there I found rather old epochs:
SV Eri: 19 Mar 1956 (HJD 2435552.109)
DX Del: 29 Aug 1966 (HJD 2439367.34000)
The GCVS on the web also has some old epochs. Can more recent epochs be found elsewhere, or are epochs from ca 50 years ago still useful for calculating times of maxima?
