amnferguson/sims_maf_notebooks

Repo with iPython notebooks and other examples for 2015 cadence workshops

This repository contains a set of sims_maf ipython notebooks, demonstrating various uses and capabilities of MAF.

Most of these notebooks assume you have installed and setup the LSST simulations package (sims_maf version >= 1.0). For instructions on installing and setting up MAF see here: https://confluence.lsstcorp.org/display/SIM/MAF+Installation+and+Initial+Examples

These notebooks require the OpSim sqlite database enigma_1189_sqlite.db, it can be downloaded from here: http://ops2.tuc.noao.edu/runs/enigma_1189/data/enigma_1189_sqlite.db.gz

Notebook Summaries

Introductory Notebooks

• IntroductionNotebook.v3.ipynb: Our introductory notebook, including installation instructions.
• Slicers.v3.ipynb: Shows how the same metric can be run with three different slicers to produce different outputs.
• TestNotebook.v3.ipynb: Test that ipython is working and you can load the MAF modules. (Optional notebook, could be useful if you are wondering about ipython and your notebook environment).

Advanced Capabilities

• Stackers.v3.ipynb: Example of calculating and adding a new column to the OpSim output "on-the-fly" with MAF. Here, we calculate the hour angle of each pointing and then look at the distribution. The Dithers notebook (below) may also be helpful to understand Stackers.
• UsingMetricBundleData.v3.ipynb: Example of restoring analysis results from disk, and then adjusting and combining plots. The data used in this notebook can be generated by the NVisitsCoadd_AllFilters_DitherComparison.v3.ipynb notebook.
• WritingNewMetric.v3.ipynb: A guide on how you can write and add your own algorithm into MAF by sub-classing an existing metric.

Static Science Notebooks

• DepthGoodSeeing.v3.ipynb: Using SQL constraints to compare coadded depth and coadded depth of only visits taken under good seeing conditions.
• DepthPerYear.v3.ipynb: An example of using SQL constraints to see the evolution of the coadded depth through the survey.
• Dithers.v3.ipynb: MAF includes several potential dithering schemes. This notebook demonstrates those dither patterns and compares their effect on the resulting power spectrum.
• NVisitsCoadd_AllFilters_DitherComparison.v3.ipynb: Examines the number of visits in each filter as well as comparing dithered and undithered surveys, with various plotting schemes. The results of this notebook can also be examined at http://ewok.astro.washington.edu:8080/allMetricResults?runId=1

Solar System and Astrometry Notebooks

• AstrometryMetrics.v3.ipynb: Example of running our proper motion and parallax metrics.
• Solar System metrics Prototype of solar system style metrics, available from the MafSSO repository.

Transient Notebooks

• TransientMetric.v3.ipynb: Example of our transient metric where you can set a simple transient light-curve shape and set a variety of detection criteria to measure the fraction of such transients LSST can recover.

Variable Notebooks

• Our variable metrics are in the sims_maf_contrib repo. A notebook example of them can be found here.
• Time delay lens challenge metrics are in the sims_maf_contrib repo. A notebook example of them can be found here.

etc

• Completeness_complexMetric.v3.ipynb: An example of the completeness metric which measures how many observations a field received compared to how many were requested.
