Total Power Map to Visibilities (TP2VIS): Joint Deconvolution of ALMA
  12m, 7m, and Total Power Array Data
  We present a new package for joint deconvolution of ALMA 12m, 7m, and Total
Power (TP) data, dubbed ``Total Power Map to Visibilities (TP2VIS)". It
converts a TP (single-dish) map into visibilities on the CASA platform, which
can be input into deconvolvers (e.g., CLEAN) along with 12m and 7m
visibilities. A manual is presented in the Github repository
(https://github.com/tp2vis/distribute). Combining data from the different ALMA
arrays is a driver for a number of science topics, namely those that probe size
scales of extended and compact structures simultaneously. We test TP2VIS using
model images, one with a single Gaussian and another that mimics the internal
structures of giant molecular clouds. The result shows that the better uv
coverage with TP2VIS visibilities helps the deconvolution process and
reproduces the model image within errors of only 5% over two orders of
magnitude in flux.
