Second Layer

Many of the Viewing Opt's can be overlaid with either velocity vectors or cell indexes using the options in the 2nd Layer frame. The display format of the 2^nd Layer parameter is controlled by the current settings for that parameter. For example, if velocity vectors are to be overlaid water column TSS and the user wants to change the format and/or plotting locations of the velocities, the user must go to the Velocity view, make the desired changes and then go back to the Water Column view and redisplay the TSS concentrations. The velocity vectors will then be overlaid on the TSS plot in the new format.
