Simultaneously to an accuracy of 0.2 - 0.25 dex, comparable to the precisionĪchievable with low-resolution spectroscopy for a signal-to-noise ratio of 10.īy comparing fitting results to the stellar loci of red giants and MS stars, we Giants can be reliably determined by fitting the u-g, g-r, r-i, and i-z colors
With good photometry, photometric metallicities of red The colors of red giants are less sensitive to metallicity Systematic differences between the metallicity-dependent stellar loci of red Of main-sequence (MS) stars, the intrinsic widths of loci of red giants areĪlso found to be quite narrow, a few mmag at maximum. The stars spanĪ range of 0.55 - 1.2 mag in color g-i, -0.3 -2.5 in metallicity ,Īnd have values of surface gravity log g smaller than 3.5 dex. Spectroscopic sample of red giants in the SDSS Stripe 82 region. Sloan Digital Sky Survey (SDSS) stellar color loci of red giant stars, using a Red giant stars, by Ruoyi Zhang and 4 other authors Download PDF Abstract: In the fourth paper of this series, we present the metallicity-dependent From particle effects and color correction to A/V sync and video transitions, our tools are designed to be fast and intuitive so that artists can get their work done quickly and beautifully.Download a PDF of the paper titled Stellar loci IV. We make our plug-ins and applications because we need them for our own work. Red Giant is a company made up of filmmakers, motion designers, VFX artists and creative technologists. Our apps are available as panels in Premiere Pro. Our Plug-ins run directly in Adobe Premiere Pro CC and Adobe After Effects CC. For almost 15 years, we’ve built software for editing, motion design, color correction, and VFX used in everything from major motion pictures to worldwide television programming to web production. Red Giant develops plug-ins and applications that make the filmmaking process faster, more secure, more accurate and just more fun.
Then we make those products available for everyone else, helping artists create the perfect look that matches their story. For our own award-winning short films, we create new software to fill our needs. At Red Giant, we make tools, films and training to enrich the community of filmmakers and motion designers.
