In this paper we introduce the software package ProPane, written for the R data analysis language. ProPane combines the full range of wcslib projections with the C++ image manipulation routines provided by the CImg library. ProPane offers routines fo

SimSpin v2.6.0 -- Constructing synthetic spectral IFU cubes for comparison with observational surveys

Autor: Harborne, K. E., Serene, A., Davies, E. J. A., Derkenne, C., Vaughan, S., Burdon, A. I., Lagos, C. del P., McDermid, R., O'Toole, S., Power, C., Robotham, A. S. G., Santucci, G., Tobar, R.

In this work, we present a methodology and a corresponding code-base for constructing mock integral field spectrograph (IFS) observations of simulated galaxies in a consistent and reproducible way. Such methods are necessary to improve the collaborat

ProFit: Bayesian Profile Fitting of Galaxy Images

Autor: Robotham, A. S. G., Taranu, D. S., Tobar, R., Moffett, A., Driver, S. P.

We present ProFit, a new code for Bayesian two-dimensional photometric galaxy profile modelling. ProFit consists of a low-level C++ library (libprofit), accessible via a command-line interface and documented API, along with high-level R (ProFit) and

Reddening and metallicity maps of the Milky Way bulge from VVV and 2MASS III. The first global photometric metallicity map of the Galactic bulge

Autor: Gonzalez, O. A., Rejkuba, M., Zoccali, M., Valenti, E., Minniti, D., Tobar, R.

We investigate the large scale metallicity distribution in the Galactic bulge, using a large spatial coverage, in order to constrain the bulge formation scenario. We use the VISTA variables in the Via Lactea (VVV) survey data and 2MASS photometry, co

Reddening and metallicity maps of the Milky Way bulge from VVV and 2MASS II. The complete high resolution extinction map and implications for Bulge studies

Autor: Gonzalez, O. A., Rejkuba, M., Zoccali, M., Valenti, E., Minniti, D., Schultheis, M., Tobar, R., Chen, B.

We use the Vista Variables in the Via Lactea (VVV) ESO public survey data to measure extinction values in the complete area of the Galactic bulge covered by the survey at high resolution. We derive reddening values using the method described in Paper
