| Formål: |
Fundamental instructions in processing of astronomical
Imaging and spectroscopic data, the nature and properties
Of generic UV, optical, and IR imaging and spectroscopic
Detectors relevant for data processing, and in signal-to-noise computations, noise‐contributions, photon statistics.
The purpose aim is to enable the student to single‐handedly
Process standard imaging and (long-slit) spectral data
In future research projects. These competences lay the
Background for potential future expansion of the competences
To more advanced and complex data processing techniques
By the student and/or collaborators/advisor.
|
| Indhold: |
Standard processing techniques of generic astronomical imaging
and spectroscopic data; for the latter data there will be a focus
on long‐slit spectroscopy, thereby providing a background for
Echelle and Integral Field Spectroscopic processing. Introduction
to the fundamental issues related to the planning of data acquisition
at the telescope.
|
| Kompetence- beskrivelse: |
Upon satisfactory completion of this course the student will be able to:
Perform the necessary basic data processing of raw
Astronomical UV, optical, and IR imaging and spectral data, as obtained from the telescopes.
Perform the necessary calibration of the scientific imaging
And spectral data
Perform basic analysis of the data such as 1‐D and 2‐D photometry, velocity widths and shifts of spectral lines,
And continuum fitting.
Calculate signal‐to‐noise ratios, generate noise images and
spectra, estimate exposure times and plan the basic data taking
details for new observations.
|
| Målbeskrivelse: |
To pass this course the student must:
participate actively in the computer sessions
be able to process both imaging and long‐slit spectral
data well enough to allow the student to extract reasonable
basic measurements from the data
demonstrate the ability to critically assess the data quality, error
sources, the necessary processing and calibration tasks needed at
each processing steps, and the goodness/quality of the data
processing performed.
Submit for approval a project report on the data processing
Performed in the course.
The report requirements are outlined
under Item ‘Exam’.

| Eksamensform: |
Internal examination. Pass/No-pass evaluation.
To pass the course the student must:
be present for the majority (> 80%) of classes and actively
participate in the data processing in class, and
submit for approval a project report on the data processing
of both imaging and spectral data performed in the course.
The report (minimum of 15 pages) should address:
All the necessary steps needed and the reasons for them and
How the quality of each processing step is evaluated. The report needs to be approved by the instructors. To be approved, the report itself should be of a sufficient quality that the student or others could use it as a compendium. The report should include a sufficient amount of the material covered in the course for the reader(at the level of a starting Master’s student) to understand with ease the procedures and techniques and why they are performed.
Re-exam: same as ordinary exam. The report must be re-submitted and approved by the instructors. |

| Bemærkninger: |
This course is highly recommended for Master students in Astronomy and
Astrophysics. Students are advised to take this course as one of the very first courses during the Master’s studies.
The student may benefit from having a background equivalent to that covered by the courses ‘Statistical Physics’, ‘Electromagnetism’ (EM1, EM2), ‘Optical Physics and Laser’.
Kurset kan undervises på dansk såfremt ingen udenlandske deltagere er tilmeldt.
Students are required to bring their own laptops. The following terminal software is necessary:
Windows: Xming software is needed: http://sourceforge.net/projects/xming/
&

Linux: the X11 environment is standard and runs automatically.
MacIntosh/MACs: Starting with operating system OS 10.5 the X11 environment can be used.
This can be downloaded for free from http://xquartz.macosforge.org/landing/.
For operating systems Leopard and Lion the X11 environment is a part of OS X.
