Abstract

Early data from the GUSTO space mission in the [NII] band will be tested by looking at sequences 50 and 51. This will be achieved by calibrating these sequences and forming spectra for the observations of Eta Carinae 5 from mixers 2 and 3. Within these spectra, the [NII] emission at 1.46 THz will be searched for. Moreover, the positions of the scans within these sequences will be extracted. After performing this analysis, differences between the two sequences are found. Sequence 50 consists of two positions, a source and a reference position, separated by around 20.3 arcminutes, making it a standard Point Switch (PS) observation, while sequence 51 consists of a 9-position 16$\times$16 arcminute grid, containing 8 source positions and 1 source and reference position, making it a non-standard PS observation. The positions given from the sequences are far from the actual region of Eta Carinae 5 due to the star-tracker data being incorrectly coupled during sequences 50 and 51. In both these sequences, for mixers 2 and 3, no [NII] emission features can be found, thus indicating the absence of [NII] emission.
