Table 1. SAXS data provided to CASP participants.
Rg, Porod Exponent (PD), Mass calculated from SAXS, Theoretical Mass, Maximum Dimension (Dmax), Radius of Cross-Section (Rxc), and Volume were calculated using SCÅTTER. Rg in real space and Dmax were calculated using PRIMUS and GNOM. Quality of data (Gold, Silver, Bronze) was provided for SAXS data collected at the SIBYLS beamline (12.3.1) at the ALS. S0999 was collected at the Diamond Light Source
