General SEQUENCER Command Reference

• astrowakeup
  Sounds a loud audible alarm in the control room, and displays a big red window on the observing-system computer screen.
  Useful to alert the astronomer from within a script, when astronomer-action is required.
• playphone
  Sounds a loud audible alarm in the control room.
  Useful to alert the astronomer from within a script, when astronomer-action is required.
• seqterm
  Opens a new sequencer xterm with commmand aliases set according to the option the user chose when it started.

  These options are 1: ALFOSC, 2: FIES: 3: NOTcam, 4: StanCam, 5: MOSCA.

  The accesscode will be set to whatever was set when the last observing system was started. If another access code is needed, use the command setenv TCSACCESSCODE 12345678 to set it for this terminal.

• test-acc nnnnnn
  Tests if the TCS access code 'nnnnnn' is valid or not. If it is correct a '0' is returned. If it is wrong a '1' is returned.

Note that all the InfoSystem commands include their own help messages, which will be always authoritative, and could be more up to date than this web.

If you provide no subcommand (show, notify, etc), you'll be presented with an usage message.

In all cases, typing command help subcommand (eg. obslog help show) will provide specific and more verbose help on that subcommand.

• infosys.obslog prefix <nightprefix>
  Makes the obslog to show files from a specific night, corresponding to the nightprefix provided as input. The prefix affects all instruments.

  nightprefix can be either the keyword current (which will show the files for ongoing night), or a valid NOT FITS prefix. E.g..

  • $ infosys.obslog prefix current
  • $ infosys.obslog prefix ub11


• infosys.obslog show <instrument>
  Switches the observing log view in the info system to show the requested 'instrument' (one of ALFOSC, FIES, MOSCA, NOTCAM or STANCAM).


• infosys.talker notify <condition>
  A condition may be one of:
  • +errors
  • -errors
  • +warnings
  • -warnings

  '+condition' will activate the notification alert for that kind of messages, making an appropiate sound and popping-up a message on the observing screen to draw your attention to the talker window.

  '-condition' will deactivate such notification

  The default setup is: +errors +warnings



• infosys.talker reset
  Sets the talker filter configuration to the default one (all -debug).
  This command will be included in the startobssys


• infosys.talker show <filter> [ <filter> ... ]
  'show' accepts one or more filter definitions. A filter definition may be one of:

  all	-- Shows everything in the log
  filter_name	-- Filters out everything except 'filter_name'
  +filter_name	-- Keep current setup also showing 'filter_name' events
  -filter_name	-- Keep current setup also hiding 'filter_name' events

  filter_name can be one of: error, warning, note, debug.

  If more than one filter are specified, they will be applied in the order they've been passed. For example:

     $ infosys.talker show error +warning

  Makes the talker show only error and warning messages

• infosys.talker file <xxxx>
  The talker reads a log file to show its information. This command makes it change from one file to another.
  If 'when' is 'current', then the talker will switch to the file currently being filled.
  If 'when' is a positive integer nn (1, 2, 3, 4...), then the talker will use a the log file from nn days ago (ie. infosys.talker file 1 will make use of last night's log).
  NB: if the file being loaded is big, the operation may take a while. Be patient.
• infosys.screen <on | off>
  Switches on/off the infosys screen.
• postprocess.kill [all|alfosc|fies|mosca|notcam|stancam]
  Terminates all processes related to the postprocessing and DS9 display for a given instrument.
• system.store system id [override]
  Stores the current state of a system, where system can be any of ALFOSC,CCD8,FASU. For ALFOSC and FASU the state includes the actual wheel positions and is therefore only valid for as long as the wheel content and/or configuration is not changed. The state is stored with the name id, and if the optional flag 'override' is given, any state already defined with the name id will be overridden.
• system.restore system id [simul]
  Restores the state of a system with name id. System can be any of ALFOSC,CCD8,FASU. For ALFOSC and FASU, the state to be restored will only be valid as long as the wheel content and/or configuration is not changed since the store command was executed. If the optional flag 'simul' is given, only a simulated restore will take place.
