1. Programme - Abstract
... Programme . ... Abstract: Planetary nebulae constitute a unique source of light element abundances for individual stars in a distant stellar population. Multi-slit spectra of 50 planetary nebulae (PN) in NGC 5128 have been observed with the ESO VLT and FORS1 spectrometer. The planetary nebulae were observed in three fields covering a range of galactic radii from 2 to 19 kpc. The emission line spectra have been analysed for light element abundances (He, O, N, Ne, S, Ar). ...

4. Contingency Plans
Next: Mission Element Points-of-Contact . Previous: Mission Operations Data Transfer . ... Each mission element should ensure that their contact information remains current and notify the RSOG of any changes. ... Non-RSOG mission elements will also use the "dit" list to notify the RSOG (and all other mission elements) of unexpected events that may impact operations elsewhere, e.g., if a tracking station discovers that the spacecraft is in an unexpected configuration. ...

6. Emission molecular bands
Next: Radial velocity of the Up: Optical spectrum of IRAS04296 Previous: Observations and spectra reduction . ... However, molecular emission features are only very rarely observed in the optical spectra of PPNe. ... On the other hand, it is well known that cometary nuclei spectra show prominent Swan band emission. In both spectra of IRAS04296 we have discovered strong emission in the (0;0) and (0;1) bands of the Swan system of the molecule. ... Now consider the case of IRAS04296. ...

... These are the filter transmission, the field of view (determined by the NICMOS optics external to the dewar, in combination with the HST mirrors), the reflectivities of the various external mirrors and the transmission of the dewar window. ... The sensitivity will obviously be affected by the pixel field of view. ... Finally, the optical efficiency will be degraded further by the reflectivities of the aluminum with MgF 2 overcoated HST primary and secondary mirrors. ... Primary mirror temperature . ...
