HELP SECTION
OPTELL
Type: Adverb (String*4)
Use: To specify the operation to be used by the TELL verb.
'ABOR' Die now, reset file statuses and delete outputs
'QUIT' Die now, but save the current output results
'CHAN' Change the running parameters
Null Value: None
Verbs:
TELL......Send parameters to tasks that know to read them on the fly.
Tasks which support this capability usefully:
APCLN-----Deconvolves images with B. G. Clark CLEAN method.
Can change DOTV, NITER, beam, and other parameters.
IMAGR-----Wide-field and/or wide-frequency Cleaning / imaging.
Can change quite a few parameters. Turning TV back
on is most useful.
SCMAP-----Imaging plus self-calibration loop with editing
Can change several imaging and self-cal parameters.
SCIMG-----Full-featured imaging plus self-calibration loop with
editing. Can change imaging, editing, and self-cal
parameters.
SDCLN-----Deconvolves images with CLEAN followed by SDI
methods. Can change DOTV, NITER, beam, and other
parameters.
UTESS-----Deconvolves multiple images with maximum entropy
methods - for images of polarization. Can change
DOTV, NITER, other parameters.
VTESS-----Deconvolves multiple images with maximum entropy
methods. Can change DOTV, NITER, other parameters.
Tasks which now run too fast for TELL to be really useful:
ATLOD-----Reads ATCA data in RPFITS format into AIPS.
FILLM-----Reads VLA on-line/archive format uv data tapes
(post Jan 88). It used to be able to read the data as it
was being recorded and so needed special TELL operations
to start and stop this. Now it only reads archived data
making changing parameters while it runs inadvisable.
Tasks which support QUIT or ABOR operations only:
MCUBE-----Builds n+1 (or n) dimensional images from sets of
n-dimensional images.
M3TAR-----Translate Haystack MKIII VLBI format "A" TAR's into AIPS.
MK3IN-----Translate Haystack MKIII VLBI format "A" tapes into AIPS.
