obs_ctmo

This repo contains code to adapt the Cristina Torres Memorial Observatory in Brownsville, Texas to work with the LSST software stack.

Generate Test Images

To test the pipeline, you may want to first execute the script to generate the test fake images:

% python test_data/generate_images.py

This will create a CTMO_TEST folder inside test_data and generate 3 dark, 3 bias, 3 flat and 3 light frames with random 16-bit integer data.

Docker Image

The obs_ctmo package is under development with version 21 of the docker image of the LSST Software Stack. We provide a Dockerfile that creates an image with obs_ctmo package installed by EUPS. You can create it, by running:

% docker build --tag ctmo/lsstpipe:latest .

Create a Detachable Container

Prepare to run it in detached mode. Make sure you are in this package folder (obs_ctmo) so that pwd resolves correctly.

% docker run -itd --name ctmo \
-v `pwd`/test_data:/home/lsst/pipe \
-v `pwd`:/opt/lsst/software/stack/stack/miniconda3-py37_4.8.2-cb4e2dc/Linux64/obs_ctmo/v1 \
ctmo/lsstpipe:latest

This will create a container from the ctmo image in detached mode.

The two -v arguments are optional. The first one mounts the directory with the test data inside the container. The second will mirror the obs_ctmo package inside the EUPS manager so that it can immediately pick up the edits when it's changed (useful when debugging).

Note: Check the init.sh that summarizes most of these initial steps.

Hop In and Out the Detachable Container

From a shell on your host system, open a shell in the container with the docker exec command:

% docker exec -it ctmo /bin/bash

Your prompt is now a prompt in the container with obs_ctmo installed.

You can repeat this process, attaching to the container multiple times, to open multiple container shells. To close a container shell, terminate the session with exit.

To stop the container entirely, run this command from your host’s shell:

% docker stop ctmo

And delete the container after you no longer need it.

% docker rm ctmo

Run LSST Stack Commands

From inside the ctmo container:

$ cd ~/pipe
$ setup lsst_distrib
$ setup obs_ctmo
$ setup -j -r CTMO_TEST
$ ingestImages.py DATA $CTMO_TEST_DIR/*.fits --mode=link

You should see the ingested images in ~/pipe/DATA inside the container (test_data/DATA in your local machine.)

Note: These commands are summarized in test_data/prepare.sh.
