HELP SECTION
PANEL
Type: Task
Converts the images created by HOLOG (which replaced HOLGR) into
panel adjustments which may actually be applied to the antenna.
The input image and mask image must have the same coordinates so
that they align properly before and after application of the corners
and increments. The combination of BLC, TRC, XINC, and YINC must
produce images 128 x 128 or 256 x 256 inside PANEL.
Contours are at -5.25, -4.75, ..., -0.25, 0.25, ... 4.75 mm.
Adverbs:
INNAME......First image name. Usually V_DEV from HOLOG.
Standard defaults.
INCLASS.....First image class. Standard defaults.
INSEQ.......First image seq. #. 0 => highest.
INDISK......Disk drive # for the first image. 0 => any.
IN2NAME.....Mask image name. Usually V_AMP from HOLOG.
Standard defaults.
IN2CLASS....Mask image class. Standard defaults.
IN2SEQ......Mask image seq. #. 0 => highest.
IN2DISK.....Disk drive # for the first image. 0 => any.
BLC.........Bottom left corner 0 -> 1
TRC.........Top right corner 0 -> all
XINC........X pixel increment
YINC........Y pixel increment
OUTFILE.....Text file with panel adjustments ' ' = 'HOME:panel.adj'
DOPLOT......Which plots do you want? 0 -> 7 (all)
Bit mask - add up all that you want
= 1 raw data
= 2 adjustment map
= 4 residual map
= 8 corner definition plot with panel numbers
APARM.......(1) = 1 -> rigid panel, shift only
= 2 -> rigid panel, tilt and shift
= 3 -> flexible panel
(2) Clip level in mask image - use only pixels in the
input image for which the mask image is > APARM(2)
(3) mapsize in meters - used only if X axis not present
in header
(4) Frequency in GHz to convert phase image - used only
when header units are degrees and FREQ axis is not
present in header
(5) # pointings in 1 dimension - used only if the header
does not have the keyword VisUsed.
(6) Fraction of panel at its edges to ignore in fitting
No default, 0.0 to 0.2 allowed.
(7) UNUSED
(8) > 0 => Suppress gray-scale part of plots
(9) > 0 => Suppress contour part of plots
(10) > 0 => Suppress panel layout part of plots
INLIST......' ' -> use focus langth and ring/panel structure of the
VLA
'VLBA' -> use structure of vLBA antennas
other -> text file containing on first non-comment line
the focal length in meters in free format and
on subsequent non comment lines the number of
panels in this ring and the inner and outer
radius of this ring (in meters). Up to 10 rings
may be included. Comment lines begin with a # or
a semi-colon.
DOTV........> 0 => AIPS plots are done on the TV
TVCHAN......Gray-scale TV channel to use for gray-scale AIPS plots
GRCHAN......Graphics channel to use for labeling, contours, and
panel layout parts of AIPS plots. 0 -> 1,2,3 resp.
