Below we define the url of the loop voltage data for the GOLEM shot #22667.
The list of all available diagnostics is here http://golem.fjfi.cvut.cz/shots/0/Data.php#all_data

baseURL = "http://golem.fjfi.cvut.cz/utils/data/"
ShotNo = 26219
identifier = "loop_voltage"
url = baseURL + str(ShotNo) + '/' + identifier
baseURL = "http://golem.fjfi.cvut.cz/utils/data/"
ShotNo = 26219
identifier = "loop_voltage"
url = baseURL + str(ShotNo) + '/' + identifier
The signal data is got from an ascii file located at the url. We download the file and convert it into a Numpy array.
