VizieR Online Data Catalog: Radio to UV observations of GRB 181201A (Laskar+, 2019)

GRB181201A was discovered by the IBIS and ISGRI instruments on board the INTEGRAL satellite on 2018 December 1 at 02:38 UT (Mereghetti+ 2018GCN.23469....1M). The optical afterglow was discovered in MASTER (Lipunov+ 2010AdAst2010E..30L) Global Robotic Net observations (Podesta+ 2018GCN.23470....1P) 10s after the INTEGRAL alert and later by the Swift UV/optical telescope.

We derived aperture photometry from pipeline-processed UVOT images downloaded from the Swift data center.

Four MASTER-net observatories (MASTER-Kislovodsk, MASTER-IAC, MASTER-SAAO, and MASTER-OAFA) participated in rapid-response and follow-up observations of GRB 181201A, beginning on 2019 December 1 in the BVRI and Clear bands.

We observed the afterglow of GRB 181201A with the Gamma-Ray Burst Optical/Near-Infrared Detector (GROND) on the MPI/ESO 2.2m telescope in La Silla in Chile beginning 0.91 days after the burst in g'r'i'z'JHK filters. We also observed the afterglow with the Ohio State Multi-Object Spectrograph (OSMOS) on the 2.4m Hiltner telescope at MDM Observatory on 2018 December 4, with 120s exposures each in the BVRI bands. We obtained two later epochs of imaging using the Templeton detector on the 1.3m McGraw-Hill telescope on the nights of 2018 December 9 and 10, obtaining 4x300s each in r' and i' bands. And we obtained Liverpool Telescope (LT) imaging with the infrared/optical camera (IO:O) at ~2.7days, comprising 3x120s exposures in g'r'i' bands.

We obtained five epochs of ALMA Band 3 (3mm) observations of GRB181201A spanning 0.88 days to 29.8d after the burst through program 2018.1.01454.T (PI: Laskar). We observed the afterglow using the VLA starting 2.9days after the burst through programs 18A-088 and 18B-407 (PI: Laskar). We detected and tracked the flux density of the afterglow from 1.2GHz to 37GHz over multiple epochs until ~164 days after the burst. Finally, we observed the afterglow using the upgraded Giant Meterwave Radio Telescope (uGMRT) through program 35_065 (PI: Laskar) starting 12.5d and 13.5d after the burst in Bands 4 (center frequency 550MHz) and 5 (center frequency 1450MHz), respectively.
