| Data Release | RAW/REDUCED |
| Targets: | NGC 2915: RA = 09 48 49,
DEC = -76 41 00
NGC 5170: RA = 10 52 33, DEC = +07 32 30 |
| Mode: | LS + Grism_R600 |
| ExpTime: | 3 hr /target (Total = ~10 hrs) |
| Conditions: | Dark, seeing > 1" |
| Objective:
|
Measurement of rotation curves from H-alpha emission in dwarf dark
matter
dominated galaxies to constrain the mass distribution at large radii and probe the inner regions. |
| Coordinator: | R.Ibata/T.Broadhurst |
| NGC 2915 80% COMPLETED
NGC 5170 60% COMPLETED |
| Targets: | ~20 stars with V=20-21 |

| ExpTime: | (900-2000)s/object (Total > 10 hr) |
| Conditions: | seeing <~ 1", grey |
| Objective: | Measurement of velocities of previously microlensed stars in the LMC
to test
LMC self-lensing models (and hence the nature of the MACHOs). Goal is to obtain S/N~10 spectra with ~10 km/s accuracy for at least 10 targets. |
| Coordinator: | R.Ibata/E.Tolstoy |
