VizieR Online Data Catalog: GRB 180618A light curves (Jordana-Mitjans+, 2022)

Here, we present the GRB 180618A ultraviolet and optical photometry corresponding to the Swift UltraViolet and Optical Telescope (UVOT) white,v,b,u,uvw1,uvm2, uvw2 bands, Liverpool Telescope (LT) RINGO3 BV,R,I bands and LT IO:O g,r,i bands.

At 86s after the detection of the GRB 180618A by the Swift Burst Alert Telescope (BAT), the UVOT from the Neil Gehrels Swift Observatory started optical observations in an unfiltered band (white). Subsequently, the UVOT continued observations with the uvw1,uvm2,uvw2 ultraviolet and the v,b,u optical filters. At 202.5 s after the BAT alert, the 2-m fully robotic LT - with site at Roque de Los Muchachos Observatory (ORM, Spain) - automatically started follow-up observations with the RINGO3 three-band polarimeter and imager. The LT observations consisted of three consecutive observing sequences of 10 minutes each with the RINGO3 in three simultaneous bands (BV,R,I), followed by six single 10 s exposures with the r filter of the IO:O optical widefield camera, and two extra observing sets of 10 minutes with the RINGO3. Three 300-s exposures with the IO:O g,r,i filters were also scheduled via the LT phase2UI, and autonomously executed by the LT at 7.4x10⁴s post-burst.

The tabulated data includes the bandpass name, the mean observing time corrected by T0 (Swift trigger time), the length of the observing window and the GRB magnitudes and flux density with their uncertainties or limits. The magnitudes and the flux density are not corrected by Galactic extinction (reddening of E(B-V)=0.065+/-0.003; Schlegel et al. 1998, 1998ApJ...500..525S) or host galactic extinction (E(B-V)<0.02).
