Cookbook Recipes

These documents provide simple "recipes" (i.e., descriptions and guided examples) for common data analysis objectives using SOFIA processed data. They are generally written for a graduate student audience and are intended to be used with the Data Handbooks.

Data Tools

Data Archive

The SOFIA Science Center provides raw and calibrated data for all instruments via the Data Cycle System (DCS) Science Archive.

Data Cycle System (DCS)

SOFIA proposals and observation data are managed by the SOFIA Data Cycle System (DCS). The DCS is designed primarily to support Science and Mission Operations activities associated with Guest Observer (GO) programs for the observatory.

Atmospheric Transmission (ATRAN)

The atmospheric transmission as a function of wavelength may be obtained using the on-line Atmospheric Transmission tool (ATRAN) developed and provided to the SOFIA program by Steve Lord. The use of ATRAN is necessary for planning SOFIA high-resolution spectroscopic observations.

Target Visibility Tool

The target visibility for SOFIA can be determined using the Visibility Tool (VT), which is now available for download. (The web version is not supported.) Note that the use of VT is not a requirement, since detailed flight planning is done by the SMO staff. VT is also now an integrated feature of USPOT.


The SOSPEX tool, written by Dario Fadda and Ed Chambers, allows users to explore the final data cubes produced by the data reduction pipeline. An overview of its use can be found on the AAS poster. (See also


The FLUXER tool, written by Christof Iserlohe, allows users to fit the continuum and estimate line strengths in the final FIFI-LS data cubes.

Coming Soon

An additional tool, written by Christof Iserlohe and Bill Vacca, to determine line strengths after accounting for telluric absorption, will be posted shortly.
