Figure 1. The upper panel are the VLA TW Hya 7mm images, while the
        middle panel are residual images from a theoretical model.
        The lower panel shows the same model imaged with the VLA for (left) the 
        same low resolution beam, and then (right) the VLA + PT image with the
        EVLA sensitivity (Credit: David Wilner, CfA and Paola D'Alessio,

      Figure 2. VLA-A image at 3.6-cm of the thermal jet in L1551.
        This is believed to be a binary jet, but present resolution
        does not allow to separate the sources. The rectangles
        mark the position and extent of the binary disks in this
        system (Credit: Luis F. Rodriguez, UNAM)

      Figure 3. VLA-A image at 3.6-cm of the binary jet in HH~111.
        The faint source to the right could be a source ejected from
        the originally triple system. This image was reconstructed
        with a maximum entrophy algorithm to enhance
        resolution (Credit: Bo Reipurth, CASA).

      Figure 4. This figure shows an analysis of combined BIMA 
        and IRAM 30-m Telescope data
        of the rho Oph A core, including Class 0 object VLA 1623.  In color
        scale and contours, the figure shows a line width map of N2H+ (1-0) 
        emission, obtained though simultaneous hyperfine component fitting.  
        Previously-found millimeter continuum objects are identified by 
        triangles (Credit: James DiFrancesco, U. California, Berkeley)
