  Lemarchand and Sagan (1993) also presented a detailed description of
       the expected signal  characteristics,  as well as the most favorable
       positions in the sky to find one of  these  signals.  They also have
       compared the capability of detection of these transmissions  by each
       present and near future SETI projects.

       There have been  some proposals to search in the infrared region for
       beacon signals beamed at us (Lawton, 1971, and Townes, 1983).
