Crate gmt_lom

Giant Magellan Telescope Linear Optical Model

Optical linear transformations applied to the rigid body motions of the primary and secondary segmented mirrors of the GMT

The optical sensitivities can be downloaded from here, or they can be recomputed with the makesens binary compiled with the crseo features and run on a computer with a NVIDIA GPU.

Example

use std::iter::once;
use skyangle::Conversion;
use gmt_lom::LOM;

let m1_rbm = vec![vec![0f64; 6]; 7];
let mut m2_rbm = vec![vec![0f64; 6]; 7];
m2_rbm
    .iter_mut()
    .step_by(2)
    .for_each(|str| {
       str[3] = 1f64.from_arcsec();
       str[4] = 1f64.from_arcsec();
 });
m2_rbm[6][3] = 1f64.from_arcsec();
m2_rbm[6][4] = 1f64.from_arcsec();
let lom = LOM::builder()
    .into_iter_rigid_body_motions(once((m1_rbm, m2_rbm)))
    .build()
    .unwrap();
let tt = lom.tiptilt();
println!(" Tiptilt: {:.0?}mas", tt);
let stt = lom.segment_tiptilt();
println!("Segment tiptilt:");
println!(" - x: {:.0?}mas", &stt[..7]);
println!(" - y: {:.0?}mas", &stt[7..]);
let sp = lom.segment_piston();
println!("Segment piston:");
sp.chunks(7).enumerate().for_each(|(k, sp)| println!(" - S{}: {:.0?}nm", k + 1, sp) );
