MANIFEST IFU

A simple model for GMT MANIFEST IFU. There are 3 possible types of IFU to choose from: * a 7 hexagons IFU, * a round IFU, * a slit IFU.

The model computes the seeing image and write it to field.png and for the chosen IFU, it masks the image, write it to <hex|round|slit>_ifu_field.png and print the IFU throughput.

Usage

The throughput of a circular IFU of diameter 0.5arcsec for r0=20cm , 50degree of zenith at 800nm is found with: shell ifu --r0 20 -z 50 -b I round -d 0.5 Replacing the round IFU with a slit the same size: shell ifu --r0 20 -z 50 -b I slit -w 0.5 or with the 7 hexagons IFU shell ifu --r0 20 -z 50 -b I hex -w 0.5

Installing

To use the model, you need first to install Rust and then install the model with: shell cargo install ifu

Running

The model, with the default 7 hexagon IFU, is run with: shell ifu or run each IFU type with * 7 hexagons IFU shell ifu hex * round IFU shell ifu round * slit IFU shell ifu slit Check the model options with: shell ifu --help or check each IFU options with * 7 hexagons IFU shell ifu hex --help * round IFU shell ifu round --help * slit IFU shell ifu slit --help
