BVgri data (SN2018evt_lco_lc.dat) was acquired by the global network at Las Cumbres Observatory . Phase is days since B-band maximum MJD 58352. The photometry images from the global network were subtracted bias and corrected flat fields with the BANZAI automatic pipeline. Then the images were template-subtracted with the Saccadic Fast Fourier Transformatio (SFFT) and performed Point Spread Function (PSF) photometry using ALLFRAME.
