Data Analysis Support

In support of HST data calibration, reduction and analysis, a number of supporting documents, software tools and auxiliary information bases are maintained at STScI and elsewhere.

DrizzlePac

DrizzlePac is a software package for aligning and combining HST images. It primarily consists of AstroDrizzle and TweakReg.
 

STAK

STAK is a set of python codes that replace IRAF. The STAK project is documented via a set of Jupyter Notebook Tutorials.
 

SpecViz

SpecViz is a tool for visualization and quick-look analysis of 1D astronomical spectra built on top of SpecUtils. Specifically, it provides an interactive tool for spectral line measurements and model fitting.
 

HST Instrument Handbooks

General information about HST instruments. Instrument information can also be found on the respective instrument web pages.

HST Data Handbooks

The HST Data Handbooks describe datasets produced by each instrument aboard the Hubble Space Telescope including in depth discussion related to the display, calibration, reduction, and recommended user analysis procedures for each of the archival and currently active HST instruments.
 

Instrument Science Reports

ISRs (Instrument Science Reports) are technical reports written by the the instrument teams about various aspects of the instruments and data. They usually contain in-depth information about a specific topic related to each instrument.
 

Jitter and Pointing

Auxiliary support information on HST pointing and jitter.
