-For HSA observations using Effelsberg, see also: [[information_for_astronomers:user_guide:eb-hsa|Observations using Effelsberg as part of the High Sensitivity Array (HSA)]]+The Effelsberg 100m radio telescope takes part in observations scheduled as part of the VLBI "High Sensitivity Array(HSA). These are observations together with the NRAO VLBA and at least 2 of the following additional telescope: Effelsberg 100m, VLA (phased array), GBT, ARECIBO.\\ 
 +Effelsberg can be used at the HSA observing frequencies of  1.4/1.6, 5, 8.4, 15, 22 and 43 GHz. All these receivers have dual circular polarization. 
  
-  - Proposals must be submitted using the NRAO web proposal tool. (Select VLBA and EB in the HSA section)+  - Proposals should be submitted using the NRAO web-based proposal submission tool at the advertised NRAO proposal deadlines. (Select VLBA and EB in the HSA section for VLBA+EB only observations)
   - Use the Walker/NRAO SCHED program for making the observing schedule, available from anonymous ftp at: ftp.aoc.nrao.edu  Directory: pub/sched\\ The SCHED manual can be read at: [[http://www.aoc.nrao.edu/~cwalker/sched/sched.html]]\\ A special section on the RDBE at: [[http://www.aoc.nrao.edu/~cwalker/sched/RDBE_system.html]]   - Use the Walker/NRAO SCHED program for making the observing schedule, available from anonymous ftp at: ftp.aoc.nrao.edu  Directory: pub/sched\\ The SCHED manual can be read at: [[http://www.aoc.nrao.edu/~cwalker/sched/sched.html]]\\ A special section on the RDBE at: [[http://www.aoc.nrao.edu/~cwalker/sched/RDBE_system.html]]
-  - Effelsberg recordings will be made using the RDBE terminal and a MK5 disk recorder. Effelsberg has SCHED station name 'EB_RDBE'.\\ For further details regarding the RDBE, consult: [[https://science.nrao.edu/facilities/vlba/docs/manuals/oss/sig-path/rdbe]]+  - All Effelsberg recordings will be made using the RDBE terminal and a MK5 disk recorder, as at the VLBA itself. Effelsberg has SCHED station name 'EB_RDBE'.\\ For further details regarding the RDBE, consult: [[https://science.nrao.edu/facilities/vlba/docs/manuals/oss/sig-path/rdbe]]
   - Deposit the schedule for EB_RDBE on the ASPEN file-server in Socorro, as for the VLBA schedule; the deadline is 2 weeks before the observation. The Effelsberg schedule will be retrieved from ASPEN by Effelsberg staff.   - Deposit the schedule for EB_RDBE on the ASPEN file-server in Socorro, as for the VLBA schedule; the deadline is 2 weeks before the observation.

     * The Effelsberg Observing Friend, Uwe Bach (ubach<at>mpifr-bonn.mpg.de) must be notified if any emergency changes are made to the schedule after that time.     * The Effelsberg Observing Friend, Uwe Bach (ubach<at>mpifr-bonn.mpg.de) must be notified if any emergency changes are made to the schedule after that time.

   -  As the Effelsberg antenna beamwidth is ca. 4 times smaller than those of VLBA antennas, periodic pointing checks are essential, especially during short wavelength observations.\\ Observers should leave frequent gaps in their VLBI schedules (~10 mins each) to allow the telescope operators to make these checks. They should be about every two hours at 4cm, and more frequently at shorter wavelengths.   -  As the Effelsberg antenna beamwidth is ca. 4 times smaller than those of VLBA antennas, periodic pointing checks are essential, especially during short wavelength observations.\\ Observers should leave frequent gaps in their VLBI schedules (~10 mins each) to allow the telescope operators to make these checks.

   - Observers using NON-STANDARD frequency set-up files (i.e. not one supplied with the current version of SCHED) should contact the Effelsberg technical friend, Uwe Bach, well before the observations so that any special files can be made in good time.\\ Technical friend e-mail: ubach<at>mpifr-bonn.mpg.de   - Observers using NON-STANDARD frequency set-up files (i.e. not one supplied with the current version of SCHED) should contact the Effelsberg technical friend, Uwe Bach, well before the observations so that any special files can be made in good time.\\ Technical friend e-mail: ubach<at>mpifr-bonn.mpg.de
