A novel color calibration method of multi-spectral camera based on normalized RGB color model
Results in Physics, 2020 True-color image of Mars is important for mineral analysis. The working light source of the Mars exploration multi-spectral camera is different from the laboratory calibration light source, so that the commonly used RGB calibration method has a large ...

Clues on the evolution of the Carina dwarf spheroidal galaxy from the color distribution of its red giant stars [PDF]
, 2003 The thin red giant branch (RGB) of the Carina dwarf spheroidal galaxy appears at first sight quite puzzling and seemingly in contrast with the presence of several distinct bursts of star formation.

Testing galaxy formation models with the GHOSTS survey: The color profile of M81's stellar halo [PDF]
, 2013 We study the properties of the stellar populations in M81's outermost part, which hereafter we will term the stellar halo, using HST ACS/WFC observations of 19 fields from the GHOSTS survey.
