SAM-FP is considered to be a Restricted User Instrument. The SAM-FP is not available for the 2020B semester.
Users interested in using the SAM F-P module should get in touch with the instrument's P.I., Dra. Cláudia Mendes de Oliveira (see contact info below). Because of its very specialized nature, SAM-FP runs have been handled by the instrument team, who carry out the observations and reduce the data. The data-cubes provided to users are already corrected for bias and flat. The phase-correction is also applied by the team. Wavelength calibration and astrometric calibration are done together with the astronomer.
SOAR scheduled four nights of Early Science observations with SAM-FP from Feb 16th to Feb 19nd, 2018. As reference, the 2016 call for proposals is linked here [1], describing the technical capabilities. The publication regarding the SAM F-P is Oliveira et al 2017 [2].
Targets submitted to the SAM F-P team should follow SOAR's standard format [3] or the following format (no other format will be accepted):
# OBJECT RAJ2000 DECJ2000
AB01_XXXXX HH:MM:SS +DD:MM:SS
AB02_XXXXX HH:MM:SS +DD:MM:SS
... ... ...
AB0N_XXXXX HH:MM:SS +DD:MM:SS
were
# A : First letter of user's last name
# B : First letter of userś first name
# N : Objetc priority number
This instrument has been developed with the team’s resources and the Fabry-Perot mode is a restricted-use instrument on SOAR. As a recognition of the effort made by the team to make this instrument available to the community and to make the data ready for the user to do science with it, it is requested that the three team members be co-authors of any published work that may result from the observations .

Here is the list of filters available to use with one of the two Fabry-Perots. The filters have to be specified in the Instrument Setup Form ideally one week before the observing run since they may be in use in another instrument or even telescope.
| BTFI 5021/17 | 3” x 3” | 5020.9 | 16.5 Å |
| BTFI 6569 / 20 | 3” x 3” | 6569.2 Å | 18.6 Å |
| BTFI 6579 / 20 | 3” x 3” | 6578.8 Å | 19.9 Å |
| BTFI 6600 / 20 | 3” x 3” | 6600.5 Å | 19.3 Å |
| BTFI 6745 / 38 | 3” x 3” | 6745 Å | 38.5 Å |
| SAMI Hα Broad | 3” x 3” | 6563 Å | 75 Å |
| SAMI [SII] Broad | 3” x 3” | 6724 Å | 75 Å |
| SAMI [SII] Narrow | 3” x 3” | 6738 Å | 27 Å |
| SAMI [NI] Medium | 3” x 3” | 5189 Å | 55 Å |
| SAMI [NII] Narrow | 3” x 3” | 6583 Å | 18 Å |
We have also filters from LAM (Laboratoire d'Astrophisique du Marseille, France) and we may add information about these filters very soon.
The astronomer can also request any other filter listed in the Filters Available at SOAR [6] page. CTIO filters are also available. The main constrain is that the filters may be 3 x 3 inches squared or round with 3 inches diameter.
