VizieR Online Data Catalog: LMI and LDT observation of Berkeley 50 members (Speckert+, 2024)
Abstract
We obtained both UBV imaging data and follow-up spectroscopy with the 4.3m LDT located at Happy Jack, Arizona.
Images were taken on the LDT using the Large Monolithic Imager (LMI).The images were kindly taken by Deidre Hunter prior to starting their own observing, just as astronomical twilight ended on 2020 October 14, and consisted of a 0.5s exposure in V, a 2s exposure in B, and a 10s exposure in U. All the spectroscopy was carried out on the LDT using the DeVeny optical spectrograph. The detector is a 2048x512e2v CCD42-10 deep-depletion device with 13.5um/pixels. A 600line/mm grating blazed at 4900AA was used with a grating tilt of 26.95deg, which provided wavelength coverage from 3700-5950AA and a dispersion of 1.12AA/pixel. (2 data files).- Publication:
