NIRSpec APT Templates

A JWST observing program that uses the NIRSpec instrument is designed by using the one of the NIRSpec templates in the Astronomer's Proposal Tool (APT).

On this page

NIRSpec offers 4 observing modes: multi-object spectroscopy, IFU spectroscopy, fixed slits spectroscopy, and bright object time-series spectroscopy. Each mode has its own APT template.

Step-by-step in APT

The step-by-step instructions for using the NIRSpec observing templates in the APT are provided in the following articles:

Creating an APT observation

Words in bold italics are buttons 
or parameters in GUI tools. Bold 
style represents GUI menus/
panels & data software packages.

To create a new NIRSpec observation, create or choose an Observation Folder in the tree editor and click Add in the active GUI window. This will add a generic observation to the folder and open an observation form. The observation can be assigned a unique number and a text label (which does not need to be unique). Select NIRSpec from the Instrument drop-down parameter field. This populates the Template drop-down field with the NIRSpec templates; select one of them to continue working on the specifics of the observation.


Information on all available options and restrictions for NIRSpec templates are available in the proposal parameters NIRSpec Templates articles.
