  In this correspondence, we obtain exact recovery conditions for regularized
modified basis pursuit (reg-mod-BP) and discuss when the obtained conditions
are weaker than those for modified-CS or for basis pursuit (BP). The discussion
is also supported by simulation comparisons. Reg-mod-BP provides a solution to
the sparse recovery problem when both an erroneous estimate of the signal's
support, denoted by $T$, and an erroneous estimate of the signal values on $T$
are available.
