VizieR Online Data Catalog: Star formation rate distribution in NGC 1232 (de Souza+, 2018)
Abstract
NGC 1232 was observed on the night of 2014 January 23 (Program SO2013B-021), with the filters g', r', and Hα. The observations were carried out with the SOAR telescope using the SOAR Adaptive Module (SAM), an instrument with an installed laser-assisted adaptive optics (AO) system (Fraga et al. 2013, J/AJ/145/165). By selectively compensating for low-altitude turbulence, AO improves resolution at visible wavelengths. The instrument contains a 4kx4k pixels CCD sensor that spans a square field of 3'. The natural seeing in the V band during the observations was 0.8". With AO the V-band seeing improved to 0.55". In Hα, the seeing was 0.5" and in the g' band, 0.66". Three individual on-source integrations were carried out for each filter, of 240 s each for g' and r' and 600 s for Hα. The standard star Hiltner 600 was also observed in the three filters for flux calibration purposes.
