MOD3D: Task to make a 3D CC file from a set of facets
INNAME Input UV file name (name)
INCLASS Input UV file name (class)
INSEQ 0.0 9999.0 Input UV file name (seq. #)
INDISK Input UV file disk unit #
IN2NAME Cleaned map name (name)
IN2CLASS Cleaned map name (class)
IN2SEQ 0.0 9999.0 Cleaned map name (seq. #)
IN2DISK Cleaned map disk unit #
INVERS -1.0 46655.0 CC file version #.
NMAPS 0.0 4096.0 No. maps to use for model.
OUTNAME Output model file name
OUTCLASS Output model file name
OUTSEQ -1.0 9999.0 Output model file name
OUTDISK Output model file disk
BCOMP First CLEAN comp to sub.
1 per field.
NCOMP Last CLEAN comp to sub.
to use (0 => all)
FLUX Lowest CC component used.
BLC Bottom left corner of 1st
Clean image -> model image
TRC Top right corner -> model
Task: Computes the 3D position of all the Clean components in a set
of Clean image facets wrt the coordinate in the UV file.
It writes out a sub-image of the 1st Clean image and a 3D
CC file with all selected Clean components ready for DFT
Model images made with both values of IMAGR's DO3DIMAG
option are handled correctly, as are multi-scale images. Set
NMAPS = NFIELD * NGAUSS.
MOD3D works only on single-source files.
INNAME.....Input UV file name (name). Standard defaults.
INCLASS....Input UV file name (class). Standard defaults.
INSEQ......Input UV file name (seq. #). 0 => highest.
INDISK.....Disk drive # of input UV file.0 => any.
IN2NAME....Model map name (name). Standard defaults.
IN2CLASS...Model map name (class). Standard defaults.
IN2SEQ.....Model map name (seq. #). 0 => highest.
IN2DISK....Disk drive # of model map. 0 => any.
INVER......CC file ver. number. 0 => highest.
NMAPS......Number of image files to use for model. For multi-scale
models, set NMAPS = NFIELD * NGAUSS to include the Clean
components of the extended resolutions. If more than one
file is to be used, the NAME, CLASS, DISK and SEQ of the
subsequent image files will be the same as the first file
except that the LAST 3 or 4 characters of the CLASS will
be an increasing sequence above that in IN2CLASS. Thus,
if INCLASS='ICL005', classes 'ICL005' through 'ICLnnn'
or 'ICnnnn', where nnn = 5 + NMAPS - 1 will be used. Old
names (in which the 4'th character is not a number) are
also supported: the last two characters are '01' through
'E7' for fields 2 through 512. In old names, the highest
field number allowed is 512; in new names it is 4096.
OUTNAME....Output model image file name (name). Standard defaults.
OUTCLASS...Output model image file name (class). Standard defaults.
OUTSEQ.....Output model image file name (seq. #). 0 => highest unique.
OUTDISK....Disk drive # of output model image file. 0 => highest
BCOMP......The first clean component to process. One value is
specified for each field used.
NCOMP......Number of Clean components to use for the model, one
value per field. If all values are zero, then all
components in all fields are used. If any value is not
zero, then abs(NCOMP(i)) (or fewer depending on FLUX and
negativity) components are used for field i, even if
NCOMP(i) is zero. If any of the NCOMP is less than 0,
then components are only used in each field i up to
abs(NCOMP(i)), FLUX, or the first negative whichever
comes first. If abs(NCOMP(i)) is greater than the number
of components in field i, the actual number is used. For
NCOMP = -1,0
says to use one component from field one unless it is
negative or < FLUX and no components from any other
field. This would usually not be desirable.
NCOMP = -1000000
says to use all components from each field up to the
first negative in that field.
NCOMP = -200 100 23 0 300 5
says to use no more than 200 components from field 1, 100
from field 2, 23 from field 3, 300 from field 5, 5 from
field 6 and none from any other field. Fewer are used if
a negative is encountered or the components go below
FLUX.......Only components > FLUX in absolute value are used in the
BLC........Bottom left corner of first Clean image to be written
to the output image.
TRC........Top right corner of first Clean image to be written
to the output image
