LAMBDAR measures galaxy fluxes from an arbitrary FITS image, covering an arbitrary photometric wave-band, when provided all parameters needed to construct galactic apertures at the required locations for multi-band matched aperture galactic photometry. Through sophisticated matched aperture photometry, the package develops robust Spectral Energy Distributions (SEDs) and accurately establishes the physical properties of galactic objects. LAMBDAR was based on a package detailed in Bourne et al. (2012) that determined galactic fluxes in low resolution Herschel images.

OneCovariance calculates the covariance matrix of photometric large-scale structure surveys. It can produce the covariance matrix for all the 2-point statistics used within the Kilo-Degree-Survey (KiDS), including configuration space statistics, bandpowers, and COSEBIs. These observables are derived from projected Fourier space quantities. OneCovariance is flexible, in that it can read in the ingredients from a harmonic space covariance matrix and produce one of the mentioned statistics.
