A real quadratic analogue was recently studied by Duke, Imamo\\=glu, and T\\'oth. They showed that the coefficients of certain weight $1/2$ mock modular forms \\[  f_D = \\sum_{d>0} a(d,D) q^d, \\qquad D>0 \\] are given in terms of traces of cycle integrals of the $j$-function. Their result applies to those coefficients $a(d,D)$ for which $dD$ is not a square.
