SETUP: For service mode observations within the SOLARNET Access Program, ROSA and IBIS can be utilized either as stand alone instruments, or combined together. In the latter case, light will be split so that ROSA operates as the blue "arm" of IBIS, observing blueward of 500 nm. To optimize execution of observations, the spectral intervals accessible by either instrument will be fixed a priori. IBIS will be used in spectroscopic or spectropolarimetric mode, choosing any combination of the following filters:
Please
remember that the sustained maximum frame rate for the
IBIS acquistion is 8 fps (14 fps for single wavelength
bursts): the scanning time of each spectral line will
be proportional to the number of wavelengths sampled
within the line. Also allow for 1-2 extra s for
pre-filter change if more than one spectral line is to
be sampled. No particular limitation to the selection
of spectral sampling points is enforced; PI can select
which combination is deemed more proper to the
scientific objectives. Repetition of spectral sampling
(i.e. a number of exposures at a single wavelength
point) is also allowed in case image reconstruction is
desired for spectral data.
The spectropolarimetric mode implies both increased exposure times, and a reduction of the FOV to about half of that available in normal spectroscopic mode - hence roughly 40"x95". PIs can contact INAF staff for more information. When working in parallel with IBIS, ROSA can utilize the following broadband filters (any subset):
PROPOSAL STRUCTURE: Proposals should include up to max 2 pages, including a scientific rationale and technical requests (detailing i.e. spectral filters and wavelength sampling). PDF submission is preferred. Please try to provide the following information in your proposal:
FINAL NOTE: We expect that each scientific projects carried out in service mode will typically require observations for 1-2 days. However, the TAC has agreed that exceptional proposals might be considered for longer durations or requiring repeated observations over multiple days. We would also note that even though service-mode is expected to optimize observing efficiency, there is no guarantee that your proposal will be run, whether due to inclement weather, insufficient seeing quality, lack of suitable targets etc. |
