per-coadd PSF for unWISE forced photometry

legacysurvey

Overview

Source for Nikola-built website for the Legacy Survey.

With nikola (v7.0+) installed:

• nikola build will build the site in the output directory.
• nikola serve will start a local webserver to preview the site.

The site uses a custom theme based on nikola's built-in bootstrap3 theme. The custom theme allows us to:

• use a drop-in bootstrap.css replacement from bootswatch.
• Tweak various aspects of the generated HTML, such as titles, links and listings.

Deployment

To simplify the preparation of site for deployment, a Makefile handles several steps, so that this simple command prepares a TAR file that can be copied to NERSC:

make TAG=9.0.2

In this example, the output would be legacysurvey-9.0.2.tar.gz.

Logo

There are a few logo files in the files directory:

• logo.svg: An "Inkscape SVG" file, which is the main source.
• logo_54.png: A PNG generated by exporting the logo in Inkscape.
• logo_square.svg: Inkscape SVG file with just the logo part (no text).
• logo_square_32.ico: A favicon used in the site. Generated from the by exporting the square logo to PNG in Inkscape then converting using ImageMagick: convert logo_square_32.png logo_square_32.ico.

unwise_psf's Issues

Python3 issue or recent fitsio string handling?

I'm getting:

unwise_forcedphot failed:
Traceback (most recent call last):
  File "/Users/dstn/legacypipe/py/legacypipe/unwise.py", line 524, in unwise_phot
    W = unwise_forcedphot(wcat, tiles, use_ceres=wise_ceres, **kwargs)

    match, = np.nonzero([c.decode() == coadd_id for c in atlas['COADD_ID']])
AttributeError: 'numpy.str_' object has no attribute 'decode'

note that the type coming out of the FITS table is a numpy.str, so it doesn't have a decode. This is with the current default "pip install fitsio" version, 1.0.5.

Consider using pkg_resource to locate data files, rather than environment variable

eg,

    from pkg_resources import resource_filename
    filename = resource_filename('unwise_psf', 'etc/psf_model_w1_neo4_unwisecat.fits')
