Working in the scheduling directory is strongly discouraged. It will very likely lead to frustration and spam for any other users on the ilofar account. It is advised to prepare schedules on your local machine or in the temp folder. Once you have used the pre...

The interruptObs.sh script operates in one of two modes: focused and global. In focused mode, it will take an input schedule, determine the relevant launched instances for that schedule, and specifically shut down all related screens, tmuxes and processes. In ...

CDMT (Stokes I) Method The GPUs in ucc4 are typically used to reduce the majority of the pulsar data produced by the station into mode 5, 8x channelised, 16x downsampled Sigproc Stokes I filterbanks. This is achieved through using a python3 script, cdmtProc.p...

UPM Method Solar data is typically processed using udpPacketManager, to produce a Stokes IV output, downsampled by a factor of 256 to 1.3ms, using a set of automated scripts. The process_data.sh script can be set to process any subdirectories with data on a ...

First update everything, it’s great if this works with sudo apt update, but more than likely it won’t. Depending on the last time the packages were updated you may need to do a fresh install as many of the packages urls might be out of date. It may also be eas...

This is a more simplified version of some of the pages David made and is meant to on board new chief observer's (CO) onto. It details the pipeline used to turn voltages to filter-banks, clean and search them before archival on DIAS or Archie.  Scheduling The...

LCU Commands  Software Level  Control processes in a LOFAR station are collected in groups called software levels. The user does not need to manually start and stop a number of processes, but each level contains processes for certain actions in the station, ...

1. Antennas LOFAR station is a wide-band radio receiver, which operates at the frequency range from 10 MHz to 240 MHz. The full reception band is divided into low band (10 MHz – 90 MHz) and high band (110 MHz – 240 MHz). The frequencies in between low band an...

LOFAR stations have two types of antenna. These are the Low-Band Antenna (LBA) array and the High-Band Antenna (HBA) array. The LBA and HBA antennas receive the frequency range of 10-90 and 110-270 MHz respectively. However, the signal processing is arranged s...

As the Sun is regularly observed by I-LOFAR a script was made by Jessica Murphy to indicate the best times for observations. This script calculates the periods during which the sun is above a specified horizon angle for a given location and date. It also retr...
