I am having a problem with IRING. I am using IRING on a
VLBI data set with pixel size 0.0001 arcsec and IRING cannot
seem integrate rings smaller than 0.001 arcsec. When I tell
it to do things in pixels it works, so I think there is a
problem with significant figures (i.e. IRING cannot deal
with rings smaller than 0.001" but is fine if rings have
a radius on 1 pixel).
Here are my inputs when things are in arcseconds (have tried
various different CPARMS):
AIPS 3: IRING: Task to integrate in confocal ellipses.
AIPS 3: Adverbs Values Comments
AIPS 3: ----------------------------------------------------------------
AIPS 3: USERID 0 User ID. 0=>current user
AIPS 3: 32000=>all users
AIPS 3: INNAME 'SNXDC96 C10 ' Image name (name)
AIPS 3: INCLASS 'ICLN ' Image name (class)
AIPS 3: INSEQ 1 Image name (seq. #)
AIPS 3: INDISK 5 Disk drive #
AIPS 3: BLC *all 0 Bottom left corner of image
AIPS 3: 0=>entire image
AIPS 3: TRC *all 0 Top right corner of image
AIPS 3: 0=>entire image
AIPS 3: APARM 5 1 Orientation parameters:
AIPS 3: *rest 0 1: x - coordinate center wrt
AIPS 3: reference point in pixels
AIPS 3: 2: y - coordinate center wrt
AIPS 3: reference point in pixels
AIPS 3: 3: position angle major axis,
AIPS 3: 4: inclination of rings
AIPS 3: to plane of sky,
AIPS 3: IRING can now operate on a
AIPS 3: restricted range of
AIPS 3: azimuthal angles
AIPS 3: 5: full range of azimuthal
AIPS 3: angles to consider
AIPS 3: 0 => 360 degrees
AIPS 3: 6: central azimuthal angle
AIPS 3: of the range specified in
AIPS 3: (5)
AIPS 3: CPARM 0 0.004 Specification of rings:
AIPS 3: 0.0001 0 1 : radius inner ring (")
AIPS 3: 1 *rest 0 2 : radius outer ring (")
AIPS 3: 3 : width of each ring (")
AIPS 3: 4 : 1=>treat blanks as zero
AIPS 3: 5 : 1=>plot radial intensity
AIPS 3: 2=>plot integrated
AIPS 3: radial intensity, from
AIPS 3: inner ring outwards.
AIPS 3: 6 : bypass arcsec conversion
AIPS 3: (for non-astr. images)
AIPS 3: DOTV 1 > 0 Do plot on the TV, else
AIPS 3: make a plot file
AIPS 3: GRCHAN 0 Graphics channel 0 => 1.
