Greetings

Hello, World! This blog is targeted at professional astronomers. It aims to discuss and share useful tips and tricks in the context of data analysis, ranging from data reduction with pipelining scripts to dealing with various errors that pop up during the compilation of a software package, and from basic pure text file manipulation to making fancy plots. As an astronomer who frequently deals with data and statistics you may, in many times, find yourself entangled with with a mess of numbers, figures and text, trying to rearrange and reformat them into something sensible, just to get prepared for the next steps of your calculation. Some posts would also be tailored to open some doors for beginners using Unix-like system.

Although the author tries to present methods accurately and in detail when necessary, most discussion and comments are based on the author's personal experiences. This does not serve as formal introduction to a particular subject, but is intended to be a place where small tutorials are given focusing on the caveats and special points to note, in the hope of rescuing souls from a pool of frustrating errors and obstacles, in a friendly and relaxing manner (hopefully, limited by the author's English skill). This is also a place to gather these souls, which would eventually find comfort by realizing that the suffering is not only personal.

Brace yourself.
