Photometric optical measurements of GRB 120326A detected by SWIFT (trigger 518626)
M. H. Siegel et al (GCNC 13105) have been done using the Schmidt telescope 0.32m F/3.1
and Starlight CCD camera HX-516 applied at direct focus. 120 sec. exposure time and
2x2 binning were used for all photos. All exposure were unfiltered.
Every night flat field and dark have been captured and all images were corrected
with them. In order to capture faint objects 60 shots was added before measurement
MPO Canopus version 10.4.0.20 was used to perform differential photometry on
the reduced images.
began of period: 2012/03/26.945 - 21.3 hours after the burst.
