B_MN B_overall :

where B_overall is the global (isotropic) temperature factor that QS assigns to all atoms of the Nth search model (for example, B_M1 20.0 will assign a temperature factor of 20.0Ų to all atoms of model number 1 (corresponding to the file defined by MOD1, see page )). This only affects the electron density and molecular transform calculation, because after each Monte Carlo step the F_c's are scaled to F_o's using an overall scale and temperature factor. A value of about 20 to 30Ų would be OK for most protein work. Default 20.0Ų.
