Science Operations


LBTI observing preparation and scripting is not currently supported in the LBTO Observing Tool.

Most LBTI runs are executed in queue observing, unless by approved special requested. Expert observers generate the observing scripts, run the programs, operating the instrument, and assess data quality ensuring science needs are met according to the Readme provided. Please make sure you have included all necessary program requirements in your readme file to ensure smooth execution. A readme template is available for download here:


Provide a complete list of your targets including calibrators and all relevant information. Information required includes: a unique identifier (if possible recognized by SIMBAD), RA & DEC, target magnitude in R or I band and in science filters, separation of AO guide star in arcsec (0.0 if the science target is the AO guide star), and the R or I magnitude of the AO guide star if different from the target.  Please also include finder charts for each target including calibrators.

Weather constraints for each target should be provided.  These should be the worst observing conditions that  your observations can tolerate.   The more relaxed the constraints are, the higher the chance the program will be executed.  The weather constraints provided should include:

  • Maximum allowed seeing in arcsec: 0.8, 1.2, 2.0, no constraint
  • Transparency: photometric, spectroscopic, thin clouds, thick clouds
  • Precipitable water vapor in mm: 3mm, 6mm, no constraint

PI’s should include the observing strategy (instrument mode, required s/n, calibrations needed,  field rotation required (eg for ADI), if saturation is acceptable and if so to what separation, etc., as well as an execution time estimate. Details about observing strategies are available here, and some of the typical overheads are summarized here.

Please contact the LBTI instrument scientist if you have any questions.
