Please indicate students, e.g., by adding ’(student)’ after the name.
[ ] We/I want to apply for time under the SOLARNET ACCESS program. If yes, please check the
box to the left (cf. http://www.astro-east.org/index.php?id=454).
[ ] We/I want to apply for time under the CCI International Time Program (ITP). If yes, please
check the box to the left (cf. http://www.astro-east.org/index.php?id=454).
For allocation of observing time we have two requests:
Request 1:
[
] We will deliver a technical report on our observing campaign – if granted – within one week
after the last day of observation. This report will contain information on: names of observers and
assistants, title of project, used instruments, instrument changes, positive feedback, problem feedback,
seeing conditions, and a wish list. The report will be sent via email to vtt@kis.uni-freiburg.de.
Request 2:
[
] Please let us know about any publication that results from VTT data sets by sending the
references to Jo Bruls (bruls@kis.uni-freiburg.de).

Justification
Title of Project:
Scientific Objectives of Observing Time
(Please give a brief statement of the scientific objectives of the requested observing campaign. This information will be used to
evaluate the scientific merit and the observatory’s general capability to conduct the type of research you intend to do. Please make
sure that all necessary information is provided.)

Former projects
(If this proposal is a continuation of a former project, please provide a list of previous program titles and a brief progress report on
a separate sheet. Please include references to publications which resulted from your earlier observing programs. Apropos: Please
let us know about any publication that results from VTT data sets by sending the references to Jo Bruls (bruls@kis))

Observing Time 2014 Proposal Form
Observing requests:
Amount of time requested:
Coordinated observation:
(Please indicate if you are planning coordinated observations with other facilities.)
Impossible Dates:
(In order to make most efficient use of observing time in view of personnel limitations, the number
of reconfigurations of the telescope and its instrumentation will be limited. We therefore will group observing requests of similar
technical nature into combined periods. An attempt will be made to accommodate a very limited amount of “impossible time”
in the schedule. There is absolutely no guarantee for success of this attempt. Please keep this in mind when specifying your
restrictions above these lines. Please keep also in mind the possibility of having your observations made by a colleague in cases of
time conflicts. Thank you for your cooperation.)
3.1
Instruments
A description of the VTT instrumentation can be found at:
http://www.kis.uni-freiburg.de/index.php?id=773
Please read it carefully and then specify the needs for your observing run in the following. Please
give an overview and describe additional needs at the end of this form in Sect. 3.3. Some of the
instruments and cameras can be combined and used simultaneously.
3.1.1
TIP (Tenerife IR Polarimeter)
[
]
Wavelength range:
[
] 1040 - 1100 nm
[
] 1200 - 1260 nm
[
] 1530 - 1800 nm
TIP-I will be available at the VTT.
3.1.2
[
TESOS
[
] Intensity Mode
]
[
] VIP (Vector Imaging Polarimeter) (Stokes I, Q, U, & V)
Please contact Thomas Kentischer (tk@kis.uni-freiburg.de) if you want to use VIP. Please specify the
spectral lines you want to use in the prefilter list (cf. Sect. 3.2.2).
3.1.3
Echelle Spectrograph
[
]
Echelle grating:
[
] 63◦ Standard
[
] 62◦ Chromosphere
[
] 55◦ IR
(The number gives the blaze angle in degrees. Put a question mark if you don’t know!)
Spectral lines that you want to observe simultaneously:
You can observe up to 3 lines simultaneously. List the combination(s) that you want to use.

Remarks
I already have a predisperser mask.
I need a new prediserser mask.
Please help me calculating mask parameters.
I use the predisperser with mirror (no grating) and use filters (cf. Sect. 3.2.2).
Slit width: The image scale on the entrance slit is 4.49 arcsec/mm.
[
[
] 40 µm [ ] 60 µm
] no slit (mirror)
[
] 80 µm
[
] 100 µm (0.45”)
[
] 150 µm
Detectors in focal plane of spectrograph: cf. Sect. 3.2.1.
3.1.4
Large spectral range (low dispersion) spectrograph
3.1.5
LARS
[
[
]
]
New features at the spectrograph will be LARS (Lars is an Absolute Reference Spectrograph): a laser
frequency comb for high precision spectroscopy, which uses artificial light for accurate flat fielding. The
latter allows for very high-signal-to-noise spectroscopy. Please contact Hans-Peter Doerr (doerr@kis),
if you want to use LARS.
3.1.6
Other instruments
In case you plan to use other instruments, please describe your needs in detail here.
