Sample WIPE MAPPING session

WIPE uses most of Clean inputs. A basic WIPE Cleaning session with MAPPING is the following

CLEAN\READ UV  file.uvt          ! 1
SIC\LET MAP_SIZE 128             ! 2
SIC\LET MAP_CELL 0.5             ! 3
SIC\LET WCOL 10                  ! 4
SIC\LET MCOL[1] 10               ! 5
SIC\LET MCOL[2] 10               ! 6
SIC\LET APERTURE[1] 1.2          ! 7
SIC\LET APERTURE[2] 1.2          ! 8
SIC\LET WEIGHT_MODE N            ! 9
CLEAN\UV_MAP                     ! 10
SHOW DIRTY                       ! 11
POLYGON                          ! 12
WIPE                             ! 13
CLEAN\WRITE NEAT file.lmv-neat   ! 14
CLEAN\WRITE BEAM  file.beam      ! 15
CLEAN\WRITE DIRTY file.lmv       ! 16

1.

Read the uv table from file ``file.uvt''

2.

Specify the map size in pixels

3.

Specify the pixel size in arcseconds

4.

Select the channel to use for the weight

5.

Specify the first channel to process

6.

Specify the last channel to process

7.

Select an amplification factor that will be used for the major axis of the ellipse defining the aperture to be synthesized

8.

Select an amplification factor that will be used for the minor axis of the ellipse defining the aperture to be synthesized

9.

Specify the weighting mode to be used, Natural or Uniform

10.

Process the dirty map of selected channels

11.

Show a bitmap of the dirty image. SHOW is a symbol defined to execute a command procedure which plots the image.

12.

Define where clean or WIPE components must be searched for, using the cursor to create a polygonal area.

13.

Now enter the main part of WIPE

14.

And once all planes have been cleaned, write the neat image on a file.

15.

write the beam in a file

16.

write the dirty map in a file

Command lines 10 to 12 are optional and performed only if the user wants to define on the Dirty Map a ``Clean Box'' like support for the reconstruction process.
