The stills pipeline figure keeps its layout and adds what rc178 does: the input box lists CXI and XTC, the geometry box is the beam centre decided on the frames and, with a cell, the distance and the module placement; the pre-scan reads the saturation level; the P1 merge keeps one crystal form. RUGNUX_OVERVIEW's stills paragraph says the same in prose. Methods: §1.4 describes the stills centre and distance hypotheses, a new §1.7 the saturation level read off the frames, and a new §7.7 a given cell as a starting point, the crystal-form filter and the module placement with its gauge.
