SKYLAB S-190B ETC PHOTO QUALITY

Analyses of S190B photographs recorded on high-resolution reconnaissance films during the Skylab missions confirm the excellent performance of the ETC system. Low-contrast resolution values of 30 to 70 lpr/mm, corresponding to ground resolutions of 30 to 15m, are estimated for second-generation photographs distributed to investigators, and maximum scales of 1:50,000 to 1:100,000 are recommended for photomap products prepared from ETC photographs.
