Machines 

 LGC - Linux gateway computer, main node used to access the LCU and REALTA 

 LCU - Linux control unit, the telescope's brain, used to configure observations, accessibly only via the LGC on the ilofar user 

 ucc1 - Main recording machine 

 Paths 

 REALTA:/mnt/ucc1_recording2/data/observations/YYYY_MM_DD - recording drive path 

 REALTA:/mnt/ucc1_recording2/data/scripts - recording scripts locations 

 ilofar@LGC:~/scheduling/schedules - input schedule file folder 

 Concepts 

 Software level (swlevel)  

 

 0 - Station is shutdown 

 1 - Station has basic power 

 2 - Minimum observing mode, hardware can generate antenna correlations 

 3 - Station is fully setup and can beam-form 

 4+ are not needed in a quick-start guide 

 

 RCU Modes 

 

 3: LBA, 0 - 100MHz 

 5: HBAlo, 100 - 200MHz 

 7: HBAhi, 200 - 250MHz 

 

 Data products 

 

 BST: typically 1 second cadence data 

 XST: Antenna cross-correlations for all-sky imaging 

 CEP/REALTA Data: The 3Gbps data stream containing 5.12us data
