Introduction

This page contains additional information for the "new SHOC" aka "shocnwonder" that is now permanently mounted on the 74-inch as a secondary instrument via the 74-inch "Instrument Selector" so user should first familiarise themselves with the "Instrument Selector" wiki: wiki-link.

All the hardware for the new SHOC system is new but the underlying control software, GUI, service startup instructions, and data-folder structures etc. are identical to the old SHOC systems so user should also first familiarise themselves with the old SHOC wiki if they are not already regular SHOC users: wiki-link.

Data access

There is a automated log being generated as files appear on disk by scraping the fits headers:

https://www.saao.ac.za/~sbp/74in_SHW_ObsLogs/

As with the old SHOC systems, data can be copied as follow:

    • Open a shell on your local PC (Putty if you're using Windows or a bash/tcsh/sh if on Mac or Linux)
    • Copy the data using the following command:
       rsync -avzP shoc74in@shoc74in.suth.saao.ac.za:"/data/74in/shw/<YYYY>/<MMDD>/*.fits" /LocalFilePath
         ---- the password is that for the shoc74in accounts
  • NOTE: if the rsync command fails, try it WITHOUT the wildcard (*) and specify a specific file. Some rsync programs apparently do not support this function.
