Single fol. from Rdzogs chen text, it mentions the overall text title in a chapter (chap. 5) colophon: Rdzogs pa chen po 'khor ba rtsa ba gcod [?] pa'i rgyud. (Tauscher's article mentions a similar title, needs checking.) I guess it's the Rdzogs chen tantra more usually titled Rdzogs pa chen po rin po che 'khor ba rtsad gcod. (Dan Martin's Hurried Notes)
