Several Scenarios studied for different disk structures and dust contents
Scenario 1. Flared disk, inner radius of 3 AU. Herbig source. The disk inclination is 45°. Scenario similar to the one used during Phase A for reconstructing an image.
Scenario 2 = scenario 1 with a disk inner radius of 4 AU
Scenario 3 = scenario 1 with a disk inclination of 35°
Scenario 4 = scenario 1 with a maximum grain size three times larger.
Scenario 5 = scenario 1 where the dust grains are made up also with 10% of crystalline olivine + Forsterite material. Images for several wavelengths are computed.
Scenario 6 = scenario 5, the same case as previously where the dust grains are made up also with a percentage of crystalline material but now the olivine composed grains are distributed for R <= 6 AU.
Scenario 7 : a puffed inner region as an alternative to Scenario 1.
Scenario 8 : a case with the presence of water ice grains (to be compared with scenario 1), disk without ice grains).

Improvement of VLTI sensitivity and accuracy.
Sensitivities with MATISSE will be improved by :- the use of an external Fringe Tracking, On and Off Axis,- the continuation of the effort made to reduce the fast OPD jitters/ vibrations.
Accuracies with MATISSE will be improved by :- the use of an external Fringe Tracking,- the effort made to reduce the fast OPD jitters/ vibrations,- the pupil lateral motion monitoring,- the use of OPD jitter residuals, tip-tilt residual, pupil lateral motion information
when analysing the data.
High limiting magnitude : Urgent need to develop and test « exotic » modes : H-K blind + N fringe-tracking MR blind recording New ideas for coherencing
High dynamic range : Urgent need to open the AMBER BCD

MATISSE Characteristics
Number of beams : four, two and three also possible.
Spectral coverage : L, M, N, possible also simultaneously. Optimized for L and N.
Spectral resolution : low : 20 <R<40 in L&M at 3.5 mm; 20<R<40 in N at 10.5 mm. Medium : 350<R<550 in L&M at 3.5 mm; 150<R<250 in N at 10.5 mm. High : 800<R<1000 in L at 3.5 mm
The simultaneous coverage of the L&M bands in low and medium resolutions, and the full coverage of the L band in high spectral resolution require an external fringe tracker.
MATISSE will measure: coherent flux, visibilities, closure phases and differential phases. Differential visibilities can also be derived.
![Page 37: MATISSE - Rencontre projet Fizeau Nov. 2010. Schedule](https://reader035.vdocuments.mx/reader035/viewer/2022062409/56649eac5503460f94bb3473/html5/thumbnails/37.jpg)
2 main modes
High sensitivity Mode (High Sens) :- 2T, 3T or 4T- With dedicated sequence of photometry: the photometry is evaluated by two
means,• In the Fourier domain, by the low frequency peak,• Using dedicated long sequences of photometric recording.
- Without photometry => Phase Oriented Mode
Simultaneous Photometry Mode (Si Phot) :- 2T, 3T or 4T- Photometric channels are used, individual photometry is estimated frame by frame for
bright targets, or binned relatively to the chopping frequency.
