To run the wizard:
-
Select
Optical Pointing
from the
File
menu (Alternatively use the
crtl-o
hot key).
If you already have a defined project that is not saved (since last changed) the OT
will prompt to see if you mean to overwrite this project. Three responses are possible:
-
Yes
will completely overwrite the system view of your project,
removing any other SBs or ObsUnitSets.
-
No
will append a new optical pointing SchedBlock to the system view.
-
Cancel
will exit the wizard, doing nothing.
-
The first Wizard page prompts for the name of a disk file from which to read a
list of pointing targets. An example list may be found in the Optical Pointing Wiki page.
-
The format of this file is a tab separated list of Name Ra(deg) Dec(deg) Vis.Mag
proper motion RA (mas/yr) proper motion Dec (mas/yr) Parallax (mas). One or more
descriptive header lines are allowed to be present - if present these must finish with a
line beginning with at least two dashes "-".
-
If you have no target list to select then leave blank and move on (click
Next
).
-
The next page displays the target list read in a tabuler format. At this stage you
may edit individual targets, add new ones, or delete targets. If you did not have a
list initially then this table to be empty on entry and you must add your own.
-
The next page prompts for the name of the SchedBlock to create. This is of no
signifcance except as a memory aid for the user.
-
The next page asks for the specification for the optical camera. This consists of
two items, the filter to be used (defaults to
night
) and the minimum exposure
time to be used for each target (defaults to
2.0 seconds
).
-
The next page asks for the control parameters for this SchedBlock. These are:
-
Elevation limit below which targets should not be observed (default
15.0 degrees
)
-
Antenna tolerance (default
0.1 arcsecs
)
-
Faintest and Brightest targets to use (no defaults)
-
The Maximum time allowed for this SchedBlock, i.e. this optical pointing
run (default
1 hour
).
-
This is the last page, click on
Finish
to complete the wizard.
The wizard now creates the Schedblock. This may take a few seconds if your target list was large.
