Descripción
The scanning Fabry-Perot spectrograph could give highly accurate,
kinematical information of star forming regions (HH objects,
protoplanetary disks and large scale flows) and the dynamics of isolated
and interacting galaxies (resonances, galaxy pairs, compact groups). In
this project we are developing a high spectral resolution scanning
Fabry-Perot interferometer for the GTC 10 m telescope and the OSIRIS
instrument. The system will provide the following characteristics: high
spectral resolution data (R up to 20000) over a whole field of view of
approximate 8 × 8 arcmin, 0.125 arcsec pixel size in two spectral
ranges; 6300 to 7000 Å (galactic projects) and 8000 to 9500
Å (OTELO objects kinematics). ICOS ET100 Fabry-Perot will be used
and installed within the OSIRIS collimated beam in the filter wheel
hosting the tunable filters. Several acquisition software features have
been defined like: synchronizing Fabry-Perot scanning with image
acquisition, data cube assembly; single frame or data cube files would
be provided according to the observer data reduction process.
Fabry-Perot plates parallelism is extremely important to improve
Finesse. Our team has developed an algorithm to accomplish this task.
