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

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
