mosaic

Mosaic the 2D-images (or cubes) made with the selfcal/crosscal (or line) worker. If not available on disc, the primary beam is built by the mosaic worker, assuming a Gaussian shape with FWHM = 1.02 lambda/D.

enable

bool

Execute the mosaic worker.

mosaic_type

{“continuum”, “spectral”}

Type of mosaic to be made, either continuum (2D) or spectral (3D).

target_images

seq, optional, default = directory/first_image.fits, directory/second_image.fits

List of images to be mosaicked, with suffix of image.fits being expected.

label_in

str, optional, default = corr

For autoselection of images, this needs to match the label/label_cal setting used for the selfcal/crosscal worker (when mosaicking continuum images) or the label setting used for the line worker (when mosaicking cubes).

line_name

str, optional, default = HI

Spectral mode only – If autoselection is used to find the final cubes, this needs to match the line_name parameter used for the line worker.

use_mfs

bool, optional, default = False

Continuum mode only – If the images to be mosaicked were created using MFS, in the selfcal or crosscal worker, then this needs to be indicated via this parameter.

name

str, optional, default = ‘ ‘

The prefix to be used for output files. Default is the pipeline prefix, as set for the general worker.

domontage

Re-grid the input images, and associated beams.

enable

bool, optional, default = True

Enable the ‘domontage’ (i.e. re-gridding) segment.

cutoff

float, optional, default = 0.1

The cutoff in the primary beam. It should be a number between 0 and 1.

dish_diameter

float, optional, default = 13.5

If no continuum pb.fits are already in place, user needs to specify the dish diameter (in units of m) so that rudimentary primary beams can be created.

ref_frequency

float, optional, default = 1383685546.875

If no continuum pb.fits are already in place, user needs to specify the reference frequency (in units of Hz) so that rudimentary primary beams can be created.

report

bool, optional, default = False

(Re)generate a full HTML report at the end of this worker.

cabs

list of map, optional, default = ‘ ‘

Specifies non-default image versions and/or tags for Stimela cabs. Running with scissors: use with extreme caution.
