UV_SHORT task computes pseudo-visibilities for short or zero spacings
from a single dish table of spectra (Class table) or LMV data cube.
These pseudo visibilities are appended to the current (presumably a Mo-
saic) UV table.
Short spacings are computed when the Interferometer dish diameter is
smaller than the Single-dish diameter, Zero spacings otherwise (see HELP
UV_SHORT Zero_Spacing for this case)
For short spacings, the command performs two steps
(1) Creation of a "well behaved" map from the spectra.
(2) Extraction of UV visibilities from this map.
See HELP UV_SHORT Step_i for detailed explanations of the method steps.
With recent UV tables and Single Dish CLASS table, most parameters are
automatically determined. The only parameter to be specified remains
SHORT_SD_FACTOR (although that one may also be determined automatically
if the input single dish data set is in main-beam brightness tempera-
ture).
A parameter set to 0 value indicates the appropriate default should be
used.
