| Target: | Casertano field (F606W, 80x80"): RA = 22:53:37.3, DEC = -14:27:40 |
| Mode: | Imaging in Ks & J band |
| ExpTime: | 2hr per filter + overhead = 5hr |
| Conditions: | photometric, seeing <0.7" |
| Objective: | Test performance of NACO deep imaging on non-point sources by comparing it with an HST-WFPC2 deep field. |
| Coordinator: | M.Lehnert, A.Moorwood, P.Rosati |
| Target: | Bulge field: RA = 18:11:04.5, DEC = -31:45:49 [NIC2 image, 22x22", J-band ] [I-band WFI image] |
| Mode: | Imaging in H, Ks & J band |
| ExpTime: | Exp Times (hours, incl.overheads): 6.5 (J), 1.3 (H), 4.8 (K) [Total = 12.8] |
| Conditions: | photometric, seeing <~0.8" |
| Objective: | Reduced NICMOS imaging will be made public to allow a direct comparison of NACO and NICMOS imaging in J,H bands (photometric accuracy, depth). By complementing NICMOS data with NACO K-band data one will be able to further improve the determination of the IMF of the bulge stars. A catalog and a FITS image in H+J band of the NICMOS field is also available for such comparison (courtesy of M.Zoccali). |

| Mode: | K band imaging |
| ExpTime: | One target only, 2.5 hrs (including overhead) |
| Conditions: | clear, seeing <0.6" |
| Objective: | Study of the closest environment of QSOs |
| Coordinators: | Y.Clenet, A-M. Lagrange |
| Target: | Pluto: RA = 17:04, V=14, ang_size=0.11"; (Charon: V~=15.5) |
| Mode: | Attempt observations of occultation of a GSC star by Pluto on July 19-20. Spectrosopy in K and L bands. |
| ExpTime: | Obtaine 5-10 images/sec during the ~3 minutes of the occultation (0.1 sec individual exposures). Spectroscopic program requires a total of 3 hours. Total time needed to complete Pluto programme: 6 hours |
| Conditions: | clear, seeing <1.1" |
| Objective: |
The pluto stellar occulation of July 20th, 2002 offers a rare and
unique oppurtunity to probe the chemical composition and physical
parameters of the Pluto atmosphere (detailed and updated information
on this event can be found at this web
site, maintened by B.Sicardy). See also these detailed notes by A-M. Lagrange. NACO spectroscopy of the Pluto-Charon system in the 1.8 to 3.6 micron range will give access to important molecular absorption bands to probe composition differences between Pluto and Charon. |

| Targets: |
HD163296 RA(2000)=17:56:21.28,
DEC=-21:57:21.9 - A1 V=6.9 |
| Mode: | Coronography in H and/or K bands. Polarimetry (Wollaston prism) in H and Ks bands |
| ExpTime: | Coronography: 3 hrs total (one band only, K or H depending
on atmospheric conditions) Polarimetry: 1.5 hrs (incl. overhead, one band) |
| Conditions: | clear, seeing <0.8" |
| Objective: | Observations of proto-planetary candidates with the aim of detecting circumstellar (CS) material around young stars, measuring their sizes and asymmetries. HST observations have revealed CS disks for both HR4796 (with NICMOS, Schneider et al. 1999), and HD 163296 (with STIS, Grady et al. 2000). NACO coronographic observations will allow the CS to be imaged with a spatial resolution better than HST. NACO polarimetric observations will allow the polarized light from the disk to be separated from the unpolarized light from the star. |
