A method, apparatus, and system for an integrated solar-driven chemical plant that manages variations in solar energy are disclosed. 2, and, wherein at least 30 wt % of compounds in the Fischer-Tropsch product have at least 30 carbon atoms; separating the product of step into one or more gas oil fractions, a base oil precursor fraction and a higher boiling fraction; and performing a pour point reducing step to the base oil precursor fraction obtained in step. The provided method uses the quarter detector offset and interleaving of complementary data to achieve in plane image resolution that is similar to the high resolution axial scanning mode utilizing quarter detector offset and interleaving. A securing device couples the adapter coupler to the adapter body via at least one coupler guide.
