Class Purpose

Astronomy is an observational science -- few experiments are
possible, and theory serves more to explain than to predict new
phenomena. As a result, it is important for everyone
involved in gathering and interpreting data to understand
something about the instruments which filter our view of the
Universe. In this course, we cover the basic principles of
instrumentation and the associated techniques involved in
recovering data from distant objects. We will discuss physical
limits on ideal instruments and some of the real imperfections
that can lead to real systematic effects. The goal of this
course is to understand instrumentation as a coherent whole,
differing only in details from one part of the spectrum to
another. We will draw heavily on examples from the radio
through optical wavelengths to illustrate the basic principles of
instrumentation, but we will also discuss other parts of the
spectrum (UV, X-ray, and gamma-ray) to show how technical details
differ in these regions. This course also includes a review
of basic statistics applied to signal and data analysis.

Class Meetings

The class meets in room 0201 of the Computer & Space Sciences
Building from on Mondays and Wednesdays from 2:00-3:15.
Because of some travel commitments, a few individual classes will
be scheduled to other mutually agreeable times. Classes will
consist primarily of intensive lectures and, I hope, equally
intensive questions and discussions as we move through the course
material.

Office Hours

Questions about lecture and problem sets or other topics are
strongly encouraged. Given everyone's varied schedules, we
will do this by appointment or by random encounter. Please
come ask questions early as they emerge. The hour or two
before class on the days problem sets are due seem to be popular
times for questions, but are difficult for me as I prepare for the
lecture. My email, phone, and office number are at the top
of this page.

Grading

There will be regular (approximately biweekly) homework
assignments that will count for 40% of the course grade. You
should anticipate spending a considerable amount of time on the
problem set assignments -- this is, of course, where you will
learn the most. A number of the homework assignments
involve computer programming. As part of the coursework, I
require use of a higher-level language such as Phython, MATLAB,
IDL, or R because of their extensive data manipulation and display
capabilities. There will be two exams: a mid-term exam
which counts for 25% of the course grade and a final exam that
counts for 35%. Both examinations count as Major Grading
Events as defined by the university. A good number of the
problems on these exams will be in the format of the Qualifying
Examination for the Department of Astronomy. As is usual for
graduate classes, I expect that most students will receive an A or
B.

Attendance

Since we are not following a textbook for this class, attendance
and careful note taking is essential. If you must miss a
class, please arrange to get notes from one of your classmates and
plan to come talk with me about points you find unclear. If
you know you will be away for university-related travel or
religious holidays, please let me know as soon as possible
(technically, within the first two weeks of the semester) so we
can arrange alternate scheduling of problem sets or
exams. This same timeframe holds for students who need
accommodation for documented disabilities.

Useful texts and references

**There are no required
texts for this class. **We cover too much ground at too many
levels for one text to suffice, and purchasing an entire set of
texts would be financially ruinous. Here
is a list of my favorite reference books for this class. You may wish to build you library with
one or two of them, depending on your interests.
