### Questions to all participants ###
=== Phase-I instrument (Starbugs (fiber bundle IFU) + new MOIRCS) Specifications ===
For your science cases,
(Q1) What is the optimum spatial sampling (or diameter in arcsec of
each fiber in the bundle) and FOV of the bundle?
The followings are the baseline configurations of the fiber bundles.
(Config1): spatial sampling=0 ".2, number of fibers=37, FOV
of the bundle~1 ".4, number of bundles~26
(Config2): spatial sampling=0 ".2, number of fibers=19, FOV
of the bundle~1 ".0, number of bundles~52
(Config3): spatial sampling=0 ".2, number of fibers=61, FOV
of the bundle~1 ".8, number of bundles~16
Please select one of your preferred configuration or propose
your required configuration
(e.g., 0 ".15 sampling fibers with smaller FOV of the bundle or
smaller number of bundles).
(Q2) What is the optimum and minimum number of the fiber bundles (or
multiplicity) in the 13'.6 diameter FOV?
The baseline specifications assume that multiplicity is 26,
52, or 16 for config 1, 2, or 3, respectively.
Please select one of you preferred configuration or propose
your required number.
Please consider if your required number of multiplicity is
high enough to be unique or competitive compared with any other
instruments in 2020s.
(Q3) What is the critical wavelength range in near-infrared covered by
the Starbug system (0.9-2.0micron)?
Current baseline specification does not include K-band since
the fiber throughput severely decreases at 2.0 micron or longer.
Implementation of the K-band fiber would be very hard and expensive.
(Q4) What is the optimum spectral resolution?
The spectral resolution of the Starbugs + newMOIRCS with 0 ".2
sampling is expected to be roughly 2-3 times higher than that of
current MOIRCS with 0 ".6 slit.
(see baseline specification of the MOIRCS)
(Q5) What is the sensitivity requirement for the phase-I instrument?
Our baseline specifications assume that the sensitivity would
be around 40-50% of Keck/MOSFIRE.
=== Science Cases with the Phase-I instrument ===
(Q6) Please describe a brief observation plan for your science case
with the fiber bundle multi-object IFU.
- Number of objects / Survey area
- Fields
- Number of nights to complete your survey
- Uniqueness
(Q7) How could the proposed science cases be competitive or
complementary to the science with 30m class telescopes (e.g. TMT) or
space telescopes (e.g. JWST) in 2020s?
=== Requirements for the Phase-II instrument ===
(Q8) Please describe the requirements for Phase-II instrument
(Starbugs + dedicated spectrograph) to develop your science case.
- Fiber bundle configurations (spatial sampling, FOV of each
bundle, number of bundles in 13'.6 FOV)
- Wavelength coverage
- Spectral resolution
- Sensitivity
=== Uniqueness of the instrument ===
(Q9) What is the unique point of the fiber bundle multi-object IFU
with Starbugs compared to the imager or multi-object slit
spectrograph?
