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.
