Clone&Play DESI survey simulation sample

The following commands should be enough to simulate a small DESI patch of 100 sq. deg on cori. This will run separately a dark and a bright survey.

A notebook showing simple plots for the spatial distribution in the results plot_quicksurvey_results.ipynb.

More details can be found in readme.ipynb.

  1. Source the latest desihub packages

    source /project/projectdirs//desi/software/desi_environment.sh master

  2. Checkout the quicksurvey_example (this repository) to scratch space

    cd $SCRATCH
git clone https://github.com/desihub/quicksurvey_example
cd quicksurvey_example

  3. Generate mock target catalogs

Dark 

select_mock_targets --no-spectra --nproc 4 --nside 16 --seed 10 \
    -c $SCRATCH/quicksurvey_example/targets/no_spectra/dark/input.yaml \
    --output_dir $SCRATCH/quicksurvey_example/targets/no_spectra/dark \
    --tiles $SCRATCH/quicksurvey_example/survey/subset_tiles_dark.fits

Bright

select_mock_targets --no-spectra --nproc 4 --nside 16 --seed 10   \
    -c $SCRATCH/quicksurvey_example/targets/no_spectra/bright/input.yaml   \
    --output_dir $SCRATCH/quicksurvey_example/targets/no_spectra/bright  \
    --tiles $SCRATCH/quicksurvey_example/survey/subset_tiles_bright.fits

  1. Combine individual healpix files into the full catalog

    join_mock_targets --mockdir $SCRATCH/quicksurvey_example/targets/no_spectra/dark
join_mock_targets --mockdir $SCRATCH/quicksurvey_example/targets/no_spectra/bright

  2. Rename the standard stars

    
mv $SCRATCH/quicksurvey_example/targets/no_spectra/dark/standards-dark.fits $SCRATCH/quicksurvey_example/targets/no_spectra/dark/standards.fits
mv $SCRATCH/quicksurvey_example/targets/no_spectra/bright/standards-bright.fits $SCRATCH/quicksurvey_example/targets/no_spectra/bright/standards.fits

6. Run quicksurvey
```bash
quicksurvey -T $SCRATCH/quicksurvey_example/targets/no_spectra/dark    \
        -E $SCRATCH/quicksurvey_example/survey/subset_exposures_dark.fits  \
        --output_dir $SCRATCH/quicksurvey_example/zcat/dark  \
        -f $(which fiberassign)    \
        -D $SCRATCH/quicksurvey_example/fiberassign/subset_dark_fiberassign_dates.txt
quicksurvey -T $SCRATCH/quicksurvey_example/targets/no_spectra/bright \
        -E $SCRATCH/quicksurvey_example/survey/subset_exposures_bright.fits \
        --output_dir $SCRATCH/quicksurvey_example/zcat/bright  \
        -f $(which fiberassign)   \
        -D $SCRATCH/quicksurvey_example/fiberassign/subset_bright_fiberassign_dates.txt
