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

4. 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

5. 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

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
