Part 5: The Second Evaluation Awaits

The fifth part of the ongoing series of my blog posts on my experience in the Google Summer of Code. I am working with Sunpy on their solar image processing toolkit, Sunkit-image. As of now two months have already and it has been an enriching experience. The second evaluation is also just around the corner and I am very hopeful that I will be able to clear it.

GSoC 2019: Project IRISpy 1.2

Four weeks have passed since the commencement of the Coding Period on May 27th, 2019 (EST). Soon our 1st evaluation will come up, which in itself is an exciting time as we will be judged on whether we will be qualified to go on to the next round. In my opinion I have done most of what have been agreed between me and my mentors. Comparing to my peers my project probably is more manageable, as an IDL version of the code already exists which provides us with a source code from which a Python-translation is written. And, the level of the project is relatively easy, so that the concepts involved are pretty basic. In this blog post, I would like to discuss about a trinity of techniques I have developed as a rookie software developer to deal with issues arising during the implementation of some new function into the broader code base. For the most up-to-date status of the PR please head to link.

Part 2: The Dive

The Coding Period of the Google Summer of Code officially began on 27th May 2019 — for me, it was the day when the “Dive” into the realm of code began.

GSoC 2019: Project IRISpy 1.1

It has been two weeks since the commencement of the coding phase… I can’t believe it, as it seems like time files. But to sum up the time that passed the following is a brief summary report for what tasks have been completed and what remains:

GSoC 2019: Project IRISpy 0.2

Progress has been better than expected… Within the past few weeks, while continuing work on the main PR (which can be accessed via this link) on enabling a time-dependent effective areas determination in the “iris_tools” file, which contains some IRIS instrument tools, most of the previous difficulties of translating from the IDL programming language to the Python language have been identified and ironed out. In hindsight, for me the hardest part was to comprehend a computing language for which I have no direct access to (as I do not have in possession a valid IDL licence), but at the same time be able to gain enough insight through freely available online documentation to check the rough work put into place earlier in another PR. Through careful and systematic checking, I have been able to move ahead and implement the new function fit_iris_xput() as well as the get_iris_response() function in a pythonic way with some heavy dose of guidance from my mentors Dr. Dan Ryan and Dr. Laura Hayes well ahead of schedule.

The Road To Google Summer Of Code

We have been taught from our childhoods that nothing can be earned without toiling hard, to achieve something we need to sacrifice something. The same mantra applies to Google Summer of Code or as we fondly know it, GSOC.

GSoC 2019: Project IRISpy 0.1

The community bonding period of this year’s GSoC is officially under way. The project I am embarking on has to do with adding a new feature to IRISpy, which is a essentially a package that is developed on top of SunPy’s NDCube package, and is written in the popular Python programming language. IRISpy itself (albeit not yet released) provides functionalities to read, manipulate, and visualize data collected with NASA’s IRIS satellite which looks at UV emission from the solar chromosphere. The proposed new feature is a time-dependent instrument response function, which will give scientists far greater power and ability to perform IRIS data analysis in Python, as well as to make new discoveries regarding the energetics and dynamics of the solar chromosphere and transition region than previously allowed. For more information on both the IRIS instrument and IRISpy, please take a look at the SunPy documentations for IRISpy.

Modeling Coronal Loops in 3D with sunpy.coordinates

The sunpy.coordinates module is a useful tool for expressing locations on the Sun in various coordinate systems. While most often used in the context of analyzing and manipulating observational data, we can also use this module to build three-dimensional models of loops in the corona.

IRISPy and NDCube

GSoC has come to an end, it was one of the best summer experience I had. In this summer I had to create a new affiliated package IRISPy but during this project making a base package for multi-dimensional contiguious and non-contiguious spatially aware arrays (from readme.md of NDCube) was a natural step so ended up developing another repository NDCube. This was initially a part of sunpycube but after breaking and burning everything we ended up with ndcube :P.

Sunpy Website Improvements

SunPy Update - October 2015

I wanted to keep people in the loop about what is happening in the SunPy project, so I thought I would start sending out monthy updates about things that have happened and things that are going to happen. This update might be a little longer than usual due to the fact it’s the first one, and I want to get everyone up to speed. Before I start I just wanted to introduce myself just incase any of you have had the fortune of not knowing. I am Stuart Mumford, I submitted my PhD thesis last week at the University of Sheffield. I am currently lead developer of the SunPy project (again) having taken over from Albert.

ESA Summer of Code

I am happy to announce that for the third year running SunPy has got a summer student from ESA’s SOCIS program. This year the student is Tomas Meszaros. Tomas’ project this summer will be working on creating a new core data type for SunPy, the HyperMap. Which will be designed to hold ND data with at least one spatial dimension and any combination of other axes such as Wavelength, Temperature or Time. This data type will allow us to support data from instruments such as Hinode EIS and the newly launched IRIS satellite, as well as a multitude of high resolution ground based instruments. Tomas will be documenting his progress on his blog: http://examon.wordpress.com as well as less regular more general interest posts on this site.
