Observing Bit Mode
There are 3 available bit modes available while observing with the station. 4, 8 and 16-bit, each of which describe the size of the signed word of each beamlet sample. 8-bit is the standard mode used for observations with I-LOFAR. Adjusting the bit mode of th...
NUMA-Aware Update
Given we're often stuck with a full drive or want to start transferring data to collaborators while observations are on-going, I had a look into the NUMA setup of UCC1 to see if we could try keep recording processing on one NUMA node and offloading on another ...
Single Pulse Source Observations
FRBs and RRats are highly transient by their nature. As a result, we could see a single peak in a 10 hour observation. While keeping the raw voltages on hand can help with re-processing observations to avoid missing features due to issues in the current method...
LuMP Processing
An alternative recording method for some observations is with the LuMP software from MPIfRA. It has been used in the past for coordinated observations with FR606 and at the request of observers from the UK and Poland. Any DSPSR sub-program (dspsr, digifil, di...
PRESTO Timing
PRESTO can be used for generating timing files for use with tempo(2). To start, a standard prepfold command should be run, though to use the output archives for timing the -nosearch flag must be used, as a result you will need a well-timed target (good entry...
Oddities
When observing with the HBAs, there can be a desync between beamforming beginning and delivery of data to the LCU. As a result, always ensure there are at least 10 seconds between the end of beamforming initialisation ("Points accepted") and recording beginin...

Processing Non-Pulse-Based Observations
The backend used for CDMT is also available in a CLI, lofar_udp_extractor, which is installed on the Docker containers available on the REALTA nodes. This guide assumes you have a UDP recording (compressed or uncompressed) from Olaf Wucknitz's VLBI recording ...

Getting TOA Measurements from Single Pulses
This page describes the process to get a TOA measurement for a single pulse, assuming You know the rough TOA of the pulse The input data is a Sigproc Filterbank DSPSR and PSRCHIVE (with GUI) are available Many steps of this process are automated on REALT...
