__init__(self,
ra,
dec,
pa,
name)
Initialises the target object.
|
|
updateConfig(self,
config)
Should be called by the parent instrument object's destructor to
enable status information to be saved to file on exit.
|
|
getApparentPlace(self)
If apparent place RA and Dec have been calculated (with
updateApparentPlace()) then returns them, else returns None.
|
|
getCoords(self)
Returns the mean place FK5 J2000 RA and Dec, and the position
angle for the target, as rotator.angle objects.
|
|
getRA(self)
Returns the mean place FK5 J2000 RA and Dec, and the position
angle for the target, as rotator.angle objects.
|
|
getDec(self)
Returns the mean place FK5 J2000 RA and Dec, and the position
angle for the target, as rotator.angle objects.
|
|
getPA(self)
Returns the position angle for the target as a rotator.angle
object
|
|
setPA(self,
pa)
Sets the requested position angle.
|
|
setCoords(RA,
Dec,
PA)
Sets the mean place FK5 J2000 RA and Dec, and the requested
position angle for the target.
|
|
updateApparentPlace(self,
tdb)
Performs the precession-nutation, light deflection and annual
aberration calculations required to obtain the apparent place RA and
dec of the target, and both returns and stores the result.
|
|
unwind(self,
shiftnumber)
Changes the position angle by the argument, shiftnumber, times 90
degrees.
