Fig. 14From: A low-dispersion spectral video camera for observing lunar impact flashesThe positions of images in a video frame of a star, α And (triangle plots). The count profiles derived from these spectral images were used in our spectral flat-field correction. We show the image positions of Flash 170201 by a red solid circular symbol and a comparison star, TYC 4665-715-1, by a blue open diamond symbolBack to article page
