Writing laboratory exercise reports

A written report is required for each laboratory exercise. The front page should contain:

  • Name of the author
  • Swedish personal identity number of the author
  • E-mail address/Phone no.
  • Submission date
  • Name of the laboratory exercise
  • Course name
  • Course code (AS****)

Unless otherwise specified, the report should contain:

  • A short abstract
  • An introduction
  • Complete solution to all tasks
  • A short summary and/or discussion

More detailed instructions can be found in the document "Things to consider when writing the report". For those of you who would like to write the report in the typesetting language LaTeX, which is widely used by astronomers and physicists, you may take a look at the file report.tex (needs the figure example.ps).

Most computer exercises are carried out in a Linux environment. You can find some useful commands in the Unix/Linux command list.
