Notes. The tabulated magnitudes are given “as observed”, i.e. neither corrected for dust extinction or K-corrected.

^(*)

Rest frame epochs (assuming a redshift of 0.041) with respect to the first detection on 56 503.882 (MJD).

^(**)

K-corrections were calculated by first using the SN 2013eq spectroscopy and the snake code (SuperNova Algorithm for K-correction Evaluation) within the S3 package (Inserra et al. 2016). These values were then interpolated to all epochs of photometric observations. The K-corrections are not included in the tabulated photometry. For the SDSS-r′ and SDSS-i′ band we calculate the K-correction to the rest frame Johnson-Cousins R and I band. LT = Liverpool Telescope; GTC = Gran Telescopio CANARIAS.
