Project Rainbows

Open Science Video Tutorial

Reducing the spectroscopy data obtained from the ALFOSC instrument of the Nordic Optical Telescope (NOT).

This is part of a science research program “Obscured Quasar Environments” led by Maria Stone.

Author and Principal Investigator: Maria Stone

Part 1. Documentation and organization

When you start a project, you need to get yourself organized and start the process of not only working on the data and getting the results, but also doing the necessary steps to keep records, to document your steps. This is essential in any science projects.

Here are some points to consider.

  • Create paper and/or electronic space for keeping your records organized for the project. I usually have a paper binder and an electronic directory. I also like to have a bookmark folder on my browser with all the commonly used website links that I can just open with one click every time I start working on the project
  • Download the raw data.
  • Create a working copy of the raw data. This will allow you to start over if you mess up, so that you don’t have to worry about modifying the original files. By the way, it is very normal if you have to start over, even many times.
  • Document everything. Your steps, your ideas, your thoughts, your questions. I often create summaries of what I have done after a chunk of work or after a day of work. I do also like to write what is the next thing to do at the end of working on a project that day. I like to keep lists:
    • todo list
    • list of questions
    • things to read
  • Document practical things as well, such as
    • paths to files
    • acknowledgements-> people, funding, instruments/telescopes
  • Consider starting a draft of the manuscript as you work on your project as well.

I find it very important to document everything. If I have not touched a project, reading over my own notes brings back to the memory the skeleton of the project, so I can resume the work. It is also easier to then make presentations for seminars or summaries for grant applications, and of course the manuscript for publication itself.
