As you might all know by now - I'm heading to ESOC for the media event that ties in with the flyby and so with a lot of help from Emily and the Rosetta Science Operations Centre at ESA - I've done a flyby chart...just the imaging instruments, but it's fairly usefull. Emily's got a vertical one in the works in the same style as her excellent New Horizons timeline.

Well -
Omega Imaging capability 128 contiguous, across track fields of view, each of 1.2 mrad, corresponding to < 500 m at periapsis Spectral capability 352 contiguous spectral channels to acquire the entire spectrum from 0.36 to 5.2 µm for each resolved pixel Photometric capability SNR > 100 over the full spectral range, allowing the identification of percentage absorptions and thermal variations VIRTIS The imaging channel VIRTIS-M is required to provide a minimum signal to noise ratio (SNR) of 100 in both spectral ranges, 0.25 - 1.0 mm and 1-5 mm at the nominal sampling under the measurement baseline conditions relative to the mapping and close observation phase, which is considered as the design driver for VIRTIS-M. The high-resolution channel VIRTIS-H is required to perform high resolution spectroscopy in the spectral range between 2 and 5 mm. The above mentioned scientific requirements imply for VIRTIS-H to provide a SNR better than 100 and a minimum resolving power of 1000 to resolve molecular bands. VIRTIS-H design is driven by the requirements in both the mapping phase and the coma observation phase, that lasts until the comet is escorted to its perihelion. (from http://servirtis.obspm.fr/virtis/virtis_exp.html ) At the sort of range that Virtis will be working (i.e. not CA) - It's going to be lower res than Omega - but higher spectral res ( 3x by my guessing ) Doug |
