The MSC provides observation planning, data infrastructure, and data calibration applications for KI. This web page contains links to help you write and submit a KI proposal and access, reduce and calibrate KI data. For assistance, contact your assigned contact scientist or visit the the help desk page.

Interferometry Basics

Proposal Planning

• How to propose (UC, Caltech, UH, NASA and NOAO TACs all accept KI proposals)

NOTE: V2 and nulling sensitivities and parameters are now updated for the 2008B call for proposals. 2008B is the last semester in which new projects using the KI nuller instrument will be accepted.

• V2 mode: Instrument sensitivity and observing parameters
• Nulling mode: Instrument sensitivity and observing parameters
  

Observation Planning

Once your proposal has been accepted, you will need to prepare a schedule file. All observations with the Keck Interferometer are executed as service observing.

• getCal planning tool: manual and web interface
• Visibility Modeling Tool
  

Data Access and Archive Users
The raw data are reduced to averaged visibilities (Level 1) by the MSC and these data are available through a web interface, subject to data proprietary constraints.

• General description of data and access mechanisms
• Search for data in the Level 1 database
• List of science sources with publicly available data
• Level 1 and 2 data product descriptions
• V² data
• Nulling data

Data Analysis
The data analysis is covered in 2 stages: from raw data to visibilities is called data reduction and correcting those visibilities for the system visibility is called data calibration.

• Data Reduction
  The data reduction step is run automatically by the MSC. If you would like the reduction run with different settings, please contact your contact scientist.
