EOVSA Data Analysis Tutorial

Software

Here are some basic information on CASA and the software we are developing:

• SunCASA A wrapper around CASA for imaging and visualizing spectral imaging data of the Sun. ONLY AVAILABLE on UNIX-BASED PLATFORMS (MacOS High-Sierra and later, REDHAT 6 & 7 and equivalents)
• GSFIT
• Obtaining CASA; CASA Guides

Setup SunCASA

Setup connections to AWS server

This is Bin's personal Amazon AWS Lightsail server for testing purposes. The server has 1 CPU, 512 MB RAM, and 20 GB SSD storage. It runs CentOS 7 (1901-01) Linux.

!!!NOTE: THIS SERVER IS ONLY INTENDED FOR THE EOVSA TUTORIAL, BUT *NOT* FOR CARRYING OUT ACTUAL DATA REDUCTION!!!

• Obtain SSH Key from Bin Chen
• Put it under a secure location on your own machine.
• Follow remaining directions depending on your client machine.

Linux / Mac

Recommend to use "~/.ssh" (create if it does not exist by "mkdir ~/.ssh").

• Edit the permission of ~/.ssh and the key (here I use ~/.ssh as the directory to place your key)

chmod -R 700 ~/.ssh
chmod 400 ~/.ssh/guest_key.pem

• Log on to test AWS server (password-less)

ssh -XY -i ~/.ssh/guest_key.pem guest@3.208.184.162

Enter SunCASA

[guest@ip-172-26-0-162 ~]$ suncasa

Windows (MobaXterm)

Recommend to use "Documents\MobaXterm\home\.ssh"

• Create new session, click SSH, enter 3.208.184.162 for Remote host, guest for username.
• On advanced SSH settings tab, click Use private key, navigate to and select file guest_key.pem
• Close setup window and click the new sessions icon, which will log you in.

Enter SunCASA

[guest@ip-172-26-0-162 ~]$ suncasa

Setup SunCASA on your own machine

MacOS Mojave

If you do not have Java SE Development Kit 12 (JDK) installed on your Mac, please download the JDK installer and install it before SunCASA installation.
