Fig. 12 :   Mosaic Observing:
Using the PMAS A&G Camera graphical user interface and a modified version of the pointing procedure, it is possible to obtain accurately aligned pointings which can be used to assemble datacubes with a larger field-of-view than supplied by the standard IFU alone. For a given object, e.g. NGC5432 in the example above, one can generate "tiles" to optimally cover any regions of interest, either as a regular grid of e.g. 3x3 pointings (which would cover 48 x 48 arcsec^2 on the sky when using the 1 arcsec sampling mode), or in a tilted, or even overlapping, geometry ... see Fig.12-x
