LIST OF POSITIONER COMMANDS

The following is a list of most commands for operating Hydra. Those marked with a bullet are the ones most likely to be encountered by the typical observer. The graphical user interface has buttons which execute many of the most important commands.

NOTE: This list is currently INCOMPLETE.

HYDRA-COMMAND window commands:

setup commands:

setup field --- User level command for configuring a target field.

setup observe --- Readies the preconfigured instrument for observations.

setup comps --- Sets the instrument up for taking comparison lamps.

setup flats --- Sets the instrument up for taking dome flats.

Calibration lamp and screen commands:

screen in --- Moves the calibration screen into place for calibrations.

screen out --- Stows the calibration screen out of the way.

screen status --- Displays status information about the screen.

screen test --- Moves the screen to test its functionality.

miscellaneous commands:

coldstart --- Initializes the hardware.

gripout --- Moves the gripper out of the way for observations.

gripin --- Moves the gripper back into action.

goxy <X> <Y> --- Moves the stage to the X, Y plate position in encoder values.

gox <X> --- Moves only the X stage.

goy <Y> --- Moves only the Y stage.

goz <Z> --- Moves the Z stage to the given Z coordinate.

move <#> <X> <Y> --- Moves the fiber at position <#> to the coordinates X and Y (restricted to valid ranges and no collisions).

park <#> --- Moves fiber <#> to its park position.

status --- Allows a check of the various modes and their status.

view <#> --- Moves the gripper over to view the fiber at position <#>.

view o <#> --- Moves the gripper over to the object with number <#>.

view s <#> --- Moves the gripper over to the fiber at slit position <#>.

where --- Gives the gripper coordinates.

whereis f <#> --- Gives the coordinates of fiber <#>.

whereis o <#> --- Gives the coordinates of object <#>.

whereis s <#> --- Gives the coordinates of the fiber at slit position <#>.

xparked <#> --- Updates the fiber data base to change the stored X and Y values to the position corresponding to the park position of fiber <#>.

xstowed <#> --- Updates the fiber data base to change the stored X and Y values of fiber <#> to the position corresponding to the fiber's stow position. Use this command when manually restowing a misplaced fiber.

HYDRA-GRAPHICS window commands:

The following commands may be typed from either the COMMANDS Window or via the appropriate GRAPHICS window button.

setup field
setup observe
setup comps
setup flats
park
assign
view
whereis
targets on to display the target objects when a configuration field is loaded.
targets off to turn off the plotting of the targets.
