The aim of this assignment is to teach you how to carry out a very common programming task: reading in a bunch of data from a text file, doing something with it then writing the results out again. ... The goal of the assignment is to write a computer program which will select this sample for you. You will pick the micro-quasars to observe from a rather large catalogue, which can be found here: The catalogue is an ASCII (text) file - you can inspect it with a normal text editor. ...

Next: Equations of condition Up: Extinction and transformation Previous: Extinction and transformation . Bias can also be introduced by improper fitting procedures. For example, the reduction program known as SNOPY, used for many years at La Silla and also at La Palma, uses a simple iterative technique in which some subsets of the parameters are solved for, while others are held fixed; then the ones last solved for are held fixed, while the ones previously fixed are redetermined. ...
