Query: A characterization of the weighted weak type Coifman-Fefferman and
  Fefferman-Stein inequalities   We introduce a variant of the $C_p$ condition (denoted by $SC_p$), and show
that it characterizes weighted weak type versions of the classical
Coifman-Fefferman and Fefferman-Stein inequalities.
