LBTB call for proposals 2015B

AIP Observing Time at the LBT

The German partners in the Large Binocular Telescope have been allocated a total of about 26 nights for the 2015B semester (Sep.1, 2015 -Jan.31, 2016). The AIP share is about 30 hours or 3 nights of which half will be allocated for PEPSI and the other half will be available for general observing programs.

We hope that MODS-2 will also be offered in binocular mode but this will only be known for sure by the end of June when the last planned commissioning run has been completed. Anyway applications for this configuration are welcomed.

Intensive work on the AO mode of LUCI-2 is underway and it is hoped that LUCI-2 can be offered in the AO mode at some point in the next semester. In that case a delta-call for programs in this mode will be made.

The PEPSI commissioning is coming along very well. If you have an interesting target/project for PEPSI you are encouraged to contact Klaus Strassmeier to see if it would suitable for the science demonstration time in one of the next semesters.



  • MODS-I The optical multi-object spectrograph will be offered in the one-eyed mode, possibly the binocular mode with MODS-2 will also be available
  • LUCI-I The near-IR imager and multi-object spectrograph will be offered in the seeing limited one-eyed mode. Depending on different factors LUCI-2 might substitute for LUCI-I and also a delta-call for AO use of LUCI-2 might be made at a later date depending on commissioning progress this semester.
  • LBC The wide field optical prime focus imager will be offered in the two-eyed (red and blue) mode
  • Note that it is possible to use MODS or LUCI in parallel with LBC red.


Applications by AIP affiliates should be submitted to the e-mail address:

Deadline for applications:  8:00am, Friday, June 12, 2015



The ISC has been tasked with organizing the call for proposals and a Time Allocation Committee (TAC) has been charged by the institute management to rank the proposals according to scientific merit, but also judge their perspectives to generate visible scientific output on relatively short timescales.

Before passing the accepted programs to the observatory for implementation, there will be a Phase 2 where observing blocks for LBC and scripts and MOS masks for LUCI and MODS will have to be prepared.

The assignment of observing time is intended to be completed by the end of June and phase-2 material should be submitted before August  24'th, 2015.


We do not have a fixed format for the proposal but it should not be longer than three pages and clearly state the objective of the project and a justification for the amount of observing time requested. Please add the new coversheet to the application in pdf format. When you have filled out the template please print it to a pdf file using your browser printing function if you cannot save it directly, Alternatively you may also provide the requested information in a similar way in a similar format using your preferred text processing system.

Selection criteria for the present call:

  • Scientific merit as assessed by the TAC. Be aware that the TAC members will be from various scientific areas. Proposals avoiding jargon and expressing their cases in simple terms may find it easier to convince the TAC.
  • Perspective to generate visible and publishable scientific output on relatively short timescales.
  • High likelihood that a proposal can be completed within the current period. This criterion certainly favors short (few hours) programs over long ones. It also favors programs that are less demanding in terms of observing conditions.
    • Due to the low pressure factor for observations under marginal conditions a new category of back-up programs has been established. These programs will not be counted against our share of 'good' condition observations, so such programs are particularly welcomed! If you have such a proposal, please make it expressly clear that it belongs to this category.

Links with technical information about the LBT, the available instruments and their performance can be obtained from the LBT web pages and we also have created a new LBT resource page with additional relevant information here.



Phase-2 preparations for accepted proposals for the LBT includes a clear description of the observations to be carried out, LUCIFER scripts or LBC Observing Blocks, and the preparation of an ASCII file containing the primary constraints (coordinates, seeing, cloudiness, time constraints, etc). Note that MOS observations require MOS masks to be produced well in advance of the observing run, so data for producing the masks should be made available before August 25'th, 2015.
The Phase-2 material should be send to the e-mail address: as a gzipped tar-file.


With the best regards on behalf of the ISC,
