These parameters may appear in either expert or non-expert mode.
Keyword Posn Type Description
------- ---- ---- -----------
INP 1 UNIV Any 2D dataset or primitive array
GLOBAL.BINDS (Default binned dataset)
BGND 2 UNIV The background model dataset. A 2D
array matching the INP dataset, or a
constant value.
GLOBAL.MODEL (Default model dataset)
OUT 3 CHARACTER The name of the output source search
results file. Enter ! for none
-> GLOBAL.SSDS (Default results dataset)
Default = SRCLIST
EXPERT - LOGICAL Run PSS in expert mode? Use default
to minimise prompting
Default = NO
MODE - CHAR Processing mode. Should be one of
SEARCH, PARAM, UPLIM or UPMAP.
Hidden default = SEARCH
SOPT - CHAR The statistic to be used. Either
CASH or GAUSSIAN.
Default = CASH
PSF, MASK, AUX CHAR Control the source model psf used.
SLICE - CHAR Specification for range of image
to search.
Default = *:*,*:*
MAP - CHAR The name of the output significance
or upper limits map. Accept default
Default = ! for no map. Used for input if RESTART
(see below) is specified.
-> GLOBAL.BINDS (Default binned dataset)
SIGMIN - REAL The threshold for detection in SEARCH
mode. Can be either a single value or
a pair - one threshold for each pass.
Default = 5.0
PLIST - CHAR Source of test positions in PARAM and
UPLIM modes. See subtopic "Source
Positions" on valid replies.
- GLOBAL.SSDS (Default results dataset)
RA - CHAR Right ascension of trial position.
Used in PARAM/UPLIM modes. Type ! to
terminate.
Default = !
DEC - CHAR Declination of trail position. Used
in PARAM/UPLIM modes.
TRY_AGAIN - LOGICAL Controls whether PSS will reprompt if
no sources were found above the given
threshold. Should be set false in batch
jobs.
Hidden default = YES
FERL - CHAR In UPLIM or UPMAP mode, the confidence
level of the upper limits. In SEARCH and
PARAM mode, the flux error confidence.
Default = '1 sigma'
DEV - CHAR Controls redirection of text output.
Hidden default = TERMINAL
These parameters may appear in only in expert mode.
RESTART - LOGICAL Restart PSS in search mode using an
existing significance map.
Hidden default = NO
QBAD - LOGICAL Specified YES prevents a source in a
bad pixel
Hidden default = YES
PSFCON - LOGICAL Psf to be constant across the field?
Default = YES Default is YES unless a psf model
specification is used.
PSFPIX - INTEGER The size of the psf box. This size is
a single number if PSFCON is true, but
may specify a changing size if PSFCON
is false (in pixels).
RESCALE - LOGICAL Rescale the background model? See the
"Background Rescaling" subtopic.
Default = NO
ISCALE - REAL Initial scale factor. Only used if
RESCALE specified.
Default = 1.0
SAMPLE - INTEGER Oversampling. Only available in expert
and SEARCH modes. See subtopic for more.
Default = 1
MULREJ - REAL Multiplier for 50% enclosed energy radius
to control rejection of spurious sources.
Hidden default = 1.0
EXTEN - LOGICAL Find measure of source extension. Only
in EXPERT mode. See "Extension Test" for
more.
Default = NO
SSUB - CHAR Source subtracted dataset. Output
filename for copy of input with sources
removed. Default is not output.
-> GLOBAL.BINDS (Default binned dataset)
Default = !
DIAG - LOGICAL Switch on diagnostic mode. See subtopic
"Diagnostic mode" for details.
Hiddfen default = NO
DOPT - CHAR The diagnostic options.
ASYMMETRIC LOGICAL Produce asymmetric errors. The default is
symmetric.
Default = NO
PERL - CHAR The positional error confidence level.
More than one value can be entered.
Separate by commas.
Default = 90%
MULTI - LOGICAL Not usually prompted for.
Hidden default = NO
MLIST - CHAR Image list file.
SENSIG - REAL Mapping sensitivity level.
Default = 5.0
NOVAR - CHAR IGNORE lack of variance or invent
POISSON errors.
Default = IGNORE
VALIDATE - LOGICAL Validate input datasets.
Hidden default = NO
