Popis:	Results are reported from radio observations of three fields in the Lynx.2 area of the Leiden Berkeley Deep Survey (Windhorst et al., 1984), obtained at 6 cm with sensitivity about 15 microJy using the D configuration of the VLA on January 22, 23, and 26, 1986. The data are presented in extensive tables and graphs and characterized in detail, and optical identifications and photometry based on the observations of Kron et al. (1985) are included. Consideration is given to the spectral index distribution, possible biases in this distribution, the relationship between the spectral index distribution and the 6-cm and 21-cm flux densities, and the possible nature of the sub-mJy radio sources. 28 references.
