* RETICON CONTROL COMMANDS - @(#)rethelp.dat 2.1 04/23/99 *

 

ABORT - Allows a Reticon exposure to be erased from the integration buffer.
	Normally, the exposure can be erased only after it has been stored.
	Note that this does NOT actually erase the buffer. See also `clear'.

CLEAR - Erase the Reticon integration buffer.
	Allowed only after the exposure has been stored, or after an
	`abort' command, and even then only if the Reticon status is
	STOP.

DSTORE - Saves the Reticon integration to disk (as a FITS file).
	All applicable header parameters (integration time, etc.) are written.
	The full file path is /reticon/sitename/YEAR/MONTH/DAY/NNNN.OBJECT,
	where `YEAR' is, for example, `1988', `MONTH' might be `12', `DAY'
	could be `17', `NNNN' is the ordinal of the observation in the 
	directory, and `OBJECT' is the name in the OBJECT field.

GO ### - Start or continue an exposure for ### seconds.
	If no time is given, the exposure will continue indefinitely.
	Note that hh:mm:ss notation is acceptable: for example,
	`go 1:30' will start a 90 second exposure. See also `total'.

HELP name - prints a summary if no `name' argument, else the full information.

LRINT ## - set left/right time between updates to ## seconds.

LRSHIFT ## - set the left vs. right side pixel shift value.
	This is the number of pixels to shift the right side to the right in
	order to align with the left. The value is about -4 for the dual 
	arrays, and a larger number for the MMT split-boule array(s). The value
	is not usually changed from that read in at startup time on file
	/Realtime/lib/reticon.parameters.

NOREPEAT - cancel a repeating exposure. 
	The currently integrating exposure is unaffected.

NOSTORE - Cancels the autostore option for the current exposure.

OBJECT objname - Sets the object name in the file name and parameter keyword.
	The name is not copied into the comment block, however. Once set,
	editing the object name in the comment block will not override this
	name, but it can be reset by a catalog `SET' command, or, of course,
	another `OBJECT' command.

REPEAT ### - Repeat the current exposure ### times. 
	If no argument is given, the exposure repeats indefinitely.
	Note that the total exposure time need not be set until after
	the `repeat' command is given. However, it must be given before
	the exposure halts, or an error results.

STOP - Stops a Reticon exposure. 

WAITHALT - Wait for an exposure halt before returning to command interpreter.
	This fails if no exposure stopping time has been given, as otherwise
	you would enter an infinite loop.
