This is an FAQ page for using TRICK, from observers' perspectives.
Can I use TRICK in the LGS mode?
Yes, TRICK works in both the NGS and LGS mode.
How should I prepare LGS starlists for TRICK?
Use the same AO guide star tool at https://www2.keck.hawaii.edu/software/findChartV2/index.php.
What is the faintest IR tip tilt star I can use for TRICK?
14- 15 mag in H or K band. TRICK doesn’t go as faint as STRAP.
Do I still need an optical tip tilt star?
Yes, you still need an R band tip tilt star for target acquisition and LBWFS corrections.
How big is the TRICK detector field of view and what is the pixel scale?
The detector field of view is 102”x102” with a 50 mas pixel scale.
What is the overhead to acquire targets and close loops in TRICK?
In general, the overhead is about twice that of using optical tip tilt (STRAP) only.
