Data Analysis in IRAF - I have my spectra... NOW WHAT???

Guess what?

I am back with new IRAF!

It's been a while since my last post about Data Analysis in IRAF. We ended up with fully reduced data but they are absolutely useless if we are unable to analyze them. For this purpose, we will use the splot task for inspecting and analyzing our spectra. 

#ScienceSunday - Test Data

Did you miss IRAF?

That is great because I am back with #ScienceSunday and IRAF reduction. Today I am not gonna introduce you into some new reduction steps but I am going to upload some test data for you to try all the steps mentioned in previous posts.

#ScienceSunday - IRAF Again

Hello Everyone,

It has been a pretty long time since my last post and even longer time since my last "scientific"work. I have been stick by procrastination since EUCYS (aww sweet EUCYS) and I could not force myself to start doing something meaningful. 

Now, I want to do something that can help me with my recent or future projects, in my school or at scientific competitions. I will post it every Sunday with #ScienceSunday hashtag on my blog or Facebook so it could be used as my public research diary, inspiration for you and hopefully I stop procrastinating.

Data Analysis in IRAF - Echelle spectra reduction and calibration

Welcome back in the sweet misery of data reduction

Great news to everyone - After finishing the last step of this post you should end up with perfectly reduced data (but I would like to highlight the word should because there will be a number of steps I am not certain at all). 

Data Analysis in IRAF - First reduction steps

Hello again

After all, we are prepared for actual processing so I would like to write something about basic steps of data reduction in IRAF which should be applied to all kind of data (photometric, spectroscopic..). These steps are focused on removing the detector 'finger print'. 

***NOTE*** 
I was working with data from ESO archive, obtained from ESO VLT, specifically from its UVES spectrograph. For this reason, all the examples will be for echelle spectra from ESO. Though, main differences for other kinds of data will not be very relevant in this part of processing.

Data Analysis in IRAF - beginning

Hi,

this post (and a few more) is the reason why I created this whole blog. I would like to write something about analysis of astronomical data in IRAF software and to point out steps which were most problematic for me as a first-time-user of this program. 

Websites you should see before or during reading this blog (or before your data reduction):

IRAF Website

IRAF Forum

Really great installation manual and slit spectra reduction guide on youtube

***WARNING*** 

This is not a manual and I do not guarantee that this is exactly what you should do with your data. As the sources of all wisdom in this post were used IRAF manuals obtained mainly from this link but there is also a lot of other websites, blogs, forums etc. where I was looking for help. I hope this post will be helpful to you and if there is anything wrong/something you are not certain of feel free to send me an e-mail or leave a comment.

***NOTE*** 
If you have already installed IRAF and know the basics like what is package and how to edit task parameters you can skip the introduction and basics parts right to my next post - 'Data Analysis in IRAF - First reduction steps'.
