Safety & Alarm Systems
This is activated by pushing the red button on the box underneath the
phone in the control room or on the pendant. If you push either button
by accident (or curiosity), you can deactivate the emergency system by
pushing the button on the control box again (repeated pushing of the
pendant button has no effect). In case you are alone at the telescope,
you should wear the lone worker alarm pendant around your neck. If you
push its button, you will also activate the emergency alarm system
This is reset by first pushing the left and then the right reset
button on the LED panel on the rack in the electronics room and after
that turning first the left and then the right key below the LED panel
Remember not to step into the light-beam at the bottom of the
staircase at the telescope entrance, as it will stop the telescope.
You can find a trap door in the floor of the control room, opening
this will activate the alarm system and stop the telescope. Also,
there is a rope ladder in the dome at the south side port
At the bottom of the staircase there is a grey button. In the dome
right inside the door and in the control room on the wall to the
electronics room there is a red button. Pressing any of these buttons
will stop the telescope immediately. Remember to release the red
buttons by turning them clockwise
First aid kit
You can find one on the wall in the toilet in the service building and
in the control room on the wall besides the door to the electronics room
Residencia night porter
In case of an emergency you can call him(ext. 500), and he will be at
the telescope shortly. Usually he drives by the telescope a couple of
times per night
The telescope closes down, if the humidity is above 90%. It must be
below 90% for 20 minutes, before the telescope again can be opened.
If there is no dust in the air, you should close the lower hatch
and the side-ports if the wind speed reaches 12 m/s. Only observe
downwind if the wind speed reaches 15
m/s. Close the telescope if the wind speed reaches 20 m/s.
If there is
dust in the air, the lower hatch and the side-ports should be closed at
10 m/s and the telescope closed at 12 m/s.
These limits can be
violated for four minutes after which the telescope will shut down
automatically. If the lower hatch closes, you must close the side-ports
Rain and ice
If the humidity reaches 100% or the rain sensor senses rain, the
telescope close immediately. The telescope hatches should not be
opened, if ice can be felt on any part of the walkway hand-rail
They are 6 degrees above the horizon and 5 degrees from the zenith
When the lower hatch is closed the vignetting starts
at zenith distance of 55 degrees.
These should slide easily. If not, use one of the hexagonal wrenches to
lift them. Never force them open!
Dome and baffle flats
To take photometric dome flats find the lamp marked 'FF lamp' in the
dome, put it on the floor at the south side-port, and put the telescope
to 60 degrees.
To take spectroscopic dome flats turn on the round
tungsten lamps in the dome, and adjust their luminosity.
take baffle lamp spectroscopic flats(bluer than halogen) turn off the
guide TV, close the mirror covers, and use the switches next to the
lisa terminal. The exposure times for baffle flats are usually very
This can be found in the control room. On it you can find telephone
numbers for your astronomy/tech support and passwords for various
Automated observation log
It can be started on the instrument control computer by running the
following commands in a terminal:
- cd /data/data1
- obslog ob19\*.fits
'ob19' is the prefix for the night, 'o' refers to the 15th year using
this naming convention(i.e. 2005), 'b' refers to the second month of
the year, and '19' refers to the 19th day in the month.
If you are using NOTCam, the executable is called obslog-notcam
Service and override programs
If there are any service observations during your run (either for a
monitoring or an override program) you will be informed.
Normally there are several of these programs running and if any of
these are activated, you can find observing
instructions on the NOT web pages
In the control room is the Observer's Cookbook which will guide you
through a night of observations. Normally it is not necessary to
consult any other manuals. All the information in the Observer's
Cookbook can also be found on the NOT web pages.
TCS access code
For the instrument control program to access the TCS, e.g. to
make small offsets, it needs a code. It can be found on page 84 on the TCS info pages. It changes every day at noon.
The wall behind the lisa terminal
Here you can find closure and altitude limits, telescope, TV and
filter foci, and info on where to find the weather pages and the TCS
access code on the TCS.
Here you can find a desktop computer, a printer, a DHCP-connection for
your laptop, and a telephone
There is a phone in the control room(+34 922 405 660) and one in the
visitor's office(+34 922 405 662). Dial '0' for an outside line, and
wait for the tone. To call a number on the mountain, dial a `2'
followed by the last three digits in the number. If you call abroad,
please note it down on the call log sheet in the visitor's office
It can be found in the main room in the service building, it's number
is +34 922 405 665
Data recording and archiving
Data from the previous night can be found to the left in the bookcase
in the visitor's office. Also, the data will enter the NOT archive,
from which they can be retrieved later
Florence guest account
This will be deleted after your run unless you arrange something with
Relevant web pages
The following is our policy for use of NOT computers by

site's security and your observations:
- Any and all use of the computers indicated by NOT staff is permitted
in the pursuit of an observing run.
- Non-profit, personal use of NOT computer facilities is permitted
provided it does not interfere with observations, normal NOT work and
provided all applicable laws are followed.
- New software may not be installed on any Windows computer nor on any
Linux machine except for temporary use in the guest accounts.

- Do not set 'xhost +' on any NOT computers.
- Use 'ssh' for communications where possible.
