The following commands and syntax can be used in macros or typed directly into the command window. Use with caution - some commands are better left out of macros! For example, quit will exit a macro at the point it occurs, no further instructions in the macro will be executed. Also, if interactive is on, and ls, dir, or history are used in a macro, the macro could stop executing and wait for a carriage return.

abort
syntax: abort
Aborts 'read' and/or 'macro'-execution

Prints the list of commands

syntax: help command
Prints information about command 'command'

history
syntax: history

itime
syntax: itime time
Set the integration-time 'time' in seconds.

syntax: itime ?
Prints the actual integration-time.

kill
syntax: kill process
Sends a 'terminate' to the following subprocesses:

	process	terminates
	display	disp, ddisp, tdisp
	infowin	sawin, sewin
	satcheck	satcheck

load
syntax: load filename [n]
Loads 'n' FITS-files into the shared memory. Since the shared memory frame-buffers are unsigned short integers, the displayed values may be not correct. You also have to swtich the cycle-type to reset.read (rr).

logfile
syntax: logfile filename
Sets 'filename' as logfile name.

syntax: logfile ?
Prints name of logfile.

ls
syntax: ls [switches] [filename]
Executes 'ls' (UNIX style).

macro
syntax: macro filename
Executes the macro 'filename'. This macro-file contains commands like you use with the shell. Be carful when invoking commands like 'read', 'telescope' or 'filter' that run in the background. Make sure that the next command does not conflict with the previous or use the 'sync' command. The default-drectory for the macros is $HOME. If you want to start the macro test.mac in $HOME/macros then enter 'macro macros/test.mac'.

next
syntax: next filename
Sets 'filename' as the default-filename. This filename is used, when no filename is given with the 'save' command.

object
syntax: object text
Sets 'text' as object in the FITS-header.

syntax: object ?
Prints the actual object.

observer
syntax: observer name
Sets 'name' as observer in the FITS-header. This name is used as password for the privileged commands.

pwd
syntax: pwd

quit
syntax: quit
Leaves the MAGIC-shell and kills all subprocesses (e.g. display,infowin,satcheck ...).

read
syntax: read [n] [-c]
Read 'n' images according to the actual cycle type. Default is the 'crep' parameter. A continous read is initiated with the '-c' parameter, and continues until aborted.

satcheck
syntax: satcheck on [limit]
Switches the saturation check on. The optional limit uses absolute counts of the A/D converter. These counts range from about 10000 - 55000. The non-linearity starts at about 40000 counts, which is the default limit. If 'sound' is on, you get a accoustic warning.

syntax: satcheck off
Switches the saturation check off. This is recomended at intgration times smaller than about 150 ms.

save
syntax: save [-f n] [-l n] [-r n1 n2] [-i] [-1] [-d] [-c] [filename]
Save frames in the shared mamory according to the actual cycle type (ctype). If no filename is given, the default filename is used.

	param	effect
	-f	save from frame 'n' (= 'first frame is')
	-l	save up to frame 'n' (= 'last frame is')
	-r	save only frames from 'n1' through 'n2'.  Default is all.
	-i	save the integral of the selected frames.
	-1	write all images into one FITS-file (cube).
	-d	do not create FITS-files. Just dump the  filled shared-memory frame buffer.
	-c	overwrite existing files  (for this save-opereation only).

 

sky
syntax: sky filename
Use 'filename' for sky-subtraction in the display and use this file as SKYFRAME in the FITS-header.

sound
syntax: sound {on,off}
Enables/disables sound after some operations like 'read', 'filter', 'telescope', 'macro', or as a warning if the saturation check is on. Default is 'off'.

syntax: sound ?
Prints the sound status.

sync
syntax: sync [read] [tele] [wheel]
Waits for termination of the read, telescope, and/or filter wheel moving process.

telescope
syntax: telescope absolute hr min sec dg min sec [equinox]
Moves the telescope to the absolute position. Be carefull with negative declinations. If 'dg' = 0 'min' has to have the minus (`-`).

    alpha: 'hr' 'min' sec'
    delta: 'dg' 'min 'sec'

syntax: telescope relative dx dy
Moves the telescope 'dx' 'dy' arc-seconds.

syntax: telescope position
Returns the telescope position.

telegui
syntax: telegui [-x Xdisplay] [-f font]

    -x: X-terminal or X-server to connect
    -f: font for menus and buttons

verbose
syntax: verbose {on,off,yes,no}
If you set 'verbose yes', you will get more output to the screen. e.g. while executing a macro the system will print every command (and the line number), so you always know which macro-line is executed. Default is 'yes'.

syntax: verbose ?
Prints status of the verbose-flag.
