Headerlet Definition TSR master file TSR 2012-02: Definition of a Headerlet and Its Role in Updating WCS Information -================================================================================ +=============================================================================== +.. abstract:: + :author: Warren Hack, Nadezhda Dencheva + :date: 22 Oct 2012 + + A headerlet is a self-consistent representation of a single WCS solution for a single + exposure complete with all distortion information. FITS is the data + storage format currently supported. It has no observational data + which makes it relatively small and light to distribute. + It is, essentially, a mechanism for encapsulating WCS information + which can later be used to update the WCS of a science file and allows + improved astrometric solutions to be stored and passed around easily. + The HST archive is expected to start accepting headerlets for HST data soon. + However the implementaiton is not HST specific and FITS WCS standard, as well as + all WCS conventions implemented in pywcs are supported. + This report describes the format and contents of a headerlet + along with the software implementation and methods for creating headerlets and using them + to update the WCS of a science observation. + Contents: .. toctree:: |
