Returns non-zero status if name already exists in the catalogue.
n may be 0-5; for the Wide-Field Camera, apertures 1-4 represent the centres of the four chips, aperture 5 is the part of the autoguider chip nearest the rotator centre, and aperture 0 is the nominal aperture, in this case the centre of the science array. (In fact, since the Perkin Elmer TCS can only support nominal aperture, aperture A and aperture B, this command maps 1-4 onto aperture A)
eg:
> aperture 1
eg:
> focus 19.26
eg:
> gocat M31
Returns non-zero status if name is not found in the catalogue.

Returns non-zero status if asked to slew the telescope beyond its mechanical limits.
Usage:
> object name hh mm ss.s dd mm ss.s A|Byyyy|Jyyyy [pR pD [epoch [Px [RV]]]]
name: simple string, no spaces allowed. RA: int hours, int minutues, real seconds. Dec: int degrees, int minutes, real seconds Equinox: A for apparent, B1950 for Besselian or J2000 for Julian Proper-motions: real seconds of time/year, real seconds arc/year epoch: real year, epoch of proper motions parallax: seconds of arc radial velocity: km/s defaults> proper motions: 0 epoch: equinox parallax: 0 radial velocity: 0eg:> object NGC3628 11 20 8 13 36 30 J1997.5Returns non-zero status if insufficient parameters are given, or values are out of range.
usage: > offset ra t|T|s|S dec
eg:
> offset 20 s 10offsets by 20 arcsec in RA and 10 arcsec in DEC.
point BEGIN
which
writes a TPOINT-compatible header file in $OBSSYS/etc/point.aux, followed by
a sequence of point name
as each object is centred,
and finally point END
to close the file. Each invocation
of point name
causes the Perkin Elmer to write
to POINT.DAT etc. eg:
> point 00+00
rotate sky
theta
and rotate vertical
. The former sends the
rotator to the give sky position angle (0 < theta < 360),
and the latter to the current
parallactic angle.
eg:
> rotate sky 180
Returns non-zero status if demanded angle is out of range for a given platform.
