OT Libraries

The Observing Tool libraries contain example observations and templates e.g. commonly used configurations and sequences that may be copy-and-pasted into a your science program. Notes on how to configure the templates are contained within the observations in the OT.  The intent of these libraries is to speed the development of new science programs.

NOTE: OT 2020A+ is now the standard OT version. All older versions have been deprecated. Please update your OT if necessary!

Current Libraries can be downloaded below:

OT Library Distr.
Distribution Notes
LBT-LUCI-SL-Library-v14.0 Feb 13, 2021 Critical calibration folder updates for OT 2020A+. All flats and arcs now have lamp off elements. Notes have been added for each flat/arc configuration.  Updated N30 Calibrations.
Updated Telluric list and fixed up telluric example.
LBT-AO-ESM-ARGOS-Library-v2.8 Oct26, 2020 Critical calibration folder updates for OT 2020A+. All flats and arcs now have lamp off elements. Notes have been added for each flat/arc configuration. Note rename to AO rather than Diffraction Limited to reduce confusion.  Updated N30 calibrations for luci1.
LBT-MODS-Library-v10.24 August 21, 2020 Biases with 1X2 and 2X2 binning added, blue only grating cals for 2X2 binning added.
LBT-LBC-Library-v5.2 May 27, 2020 Calibration folder updated to include co-pointing templates for all standard fields


These libraries are ever-evolving. Because of the many options and configurations available for LUCI, recently the Library for LUCI was separated into two: Seeing-Limited and Diffraction-Limited & ESM.  Please download the most current libraries. If you find an issue please let us know.

Once you have downloaded these libraries, please import them into your working version of the OT. Instructions on how to import programs are here:


The LBT-LUCI-SL-Library contains Templates and Examples for both Imaging, Long-slit, and MOS Seeing-Limited Observations.  The library also contains templates for calibrations such as Sky Flats for a number of Blank Fields, and daytime calibrations such as Arcs, Flats, etc.



Templates each contain a note on how adjust the templates. There are detailed examples available here that demonstrate how to manipulate and alter the Library to generate typical LUCI observations.


The LUCI Imaging Examples/Templates group of the Library contain two types of observations for each LUCI:  Dither on Source (Ideal more so for sparse field imaging) & On and Off source observations (Ideal more for extended objects or crowded fields).

Each spectroscopic observation is comprised of both an acquisition and science observation.  The LUCI LongSlit Examples/Templates show a number of different types of observations for each LUCI including the standard Long-slit Dither on Source, On/Off-source, and 2 types of Blind-Offset Observations. There are also a number of templates for LUCI Fraternal observations.

The library contains templates for Long-slit Tellurics along with two lists of possible Tellurics: A0V Telluric List and G2V Telluric List. Other resources are are also available:

Gemini also has an excellent page outlining criteria for how best to select Tellurics:

The Library contains template and examples for MOS observations.  These include templates and examples of associated Telluric observations.
For all templates, use the imbedded notes and LUCI OT Example pages to help make the changes necessary to build your desired observation.
The LBT-LUCI-DL-ESM-Library contains Templates and Examples for Enhanced Seeing Mode and AO observations.  These templates do assume some familiarity with LUCI and with the OT.


The LBC Library contains templates for observing in multiple filters, both cycling through filters at each dither position and completing the dither pattern before changing filters. These can be copied and pasted into your program and altered as needed.  Please refer to the LBC OT Examples to see how to manipulate the Libraries to generate science observations.


The library also contains template observations for co-pointing scripts, only the target should need to be altered. Do not change the filters or detector configuration.
The library includes Landolt standard fields with observations for multiple filters as well as individual filters. These observations contain four dither points to place the target on the centers of each chip.Please note that calibration scripts for LBC are currently not supported through the OT. This functionality will be added in a future release.


The MODS Library contains examples and templates for imaging, longslit and MOS observations and appropriate calibrations, as well as a collection of spectrophotometric standards. See MODS OT Examples for how to construct your own programs using the library.

NOTE: Although the OT distinguishes between MODS 1 and MODS 2, the output scripts themselves are not specific and can be executed on either instrument. Only the MODS calibration scripts are instrument specific.
