4DAO is a Fortran code designed to launch DAOSPEC (Stetson & Pancino 2008) for a large sample of spectra. The software allows one to easily manage the input/output files of DAOSPEC, to optimize the main DAOSPEC parameters and to mask specific spectral regions. It also provides suitable graphical tools to evaluate the quality of the solution.

We provide the grid of binary models calculated in Xin et al. (2015) for an age of 13 Gyr and a metallicity Z=0.0001, sampling the following parameter space: (i) primary masses ranging between 0.7 and 1.1 Msol, (ii) secondary masses varying between 0.3 and 1.1 Msol, (iii) orbital separations ranging from 1.0 to 10 Rsol. These parameters cover all the possibilities of making a blue straggler star from case-B mass transfer in an old cluster as M30.

This tool allows you to obtain the average colour excess E(B-V) along the line of sight of NGC 6440, in 0.5'' x 0.5'' each, for a total field of view of 160" x 240''. Just insert the RA and Dec coordinates of your point of interest and then click the 'Calculate' button: the value of E(B-V) corresponding to your coordinates will immediately appear. For the details of how the extinction map is computed, please refere to Pallanca et al. 2019 (a PDF is also available at arXiv:).

This application builds single-mass and isotropic King (1966) and Wilson (1976) models, which are commonly considered to properly represent globular clusters. Once a value of the W_0 shape parameter is selected, various structural and morphological parameters, and the projected surface density profile of the corresponding model are immediately visualized. Scale-free radial profiles of the volume density, surface density, and line-of-sight velocity dispersion can be downloaded. The user can also include a central intermediate-mass black hole, according to the self-consistent model generalization of Miocchi (2007, MNRAS 381, 103); in this case the ratio between the black hole and the cluster mass has to be also selected by the user.

This database contains the UV colour-magnitude diagrams of 44 Galactic globular clusters and their corresponding catalogues, obtained from near-UV and far-UV observations with GALEX. All data are available for free download. The related paper "UV Properties of Galactic Globular Clusters with GALEX I. The Color-Magnitude Diagrams" (Schiavon et al. 2012) can be found in Dalessandro et al. 2012, AJ 143,121 (a PDF copy is also available at arXiv:1201.5377).

This tool allows you to obtain the average colour excess E(B-V) along the line of sight of Terzan 5, in 25 x 25 cells of 8'' x 8'' each, for a total field of view of 200" x 200''. Just insert the RA and Dec coordinates of your point of interest and then click the 'Calculate' button: the value of E(B-V) corresponding to your coordinates will immediately appear. For the details of how the extinction map is computed, please refere to Massari et al. 2012, ApJ, 755, 32 (a PDF is also available at arXiv:1209.0990).

GALA is a Fortran code for computing the stellar atmospheric parameters and chemical abundances by using the equivalent width of metallic lines, providing graphical and statistical tools to evaluate the goodness of the solution. The calculation of abundances is performed by using a modified version of the WIDTH9 code (originally developed by R. Kurucz). Details about GALA are decribed in Mucciarelli et al. 2013, ApJ 766, 78 (a PDF copy is also available at arXiv:1302.3618).

This database contains the projected density profiles obtained from resolved star counts for a sample of 26 Galactic globular clusters. The observed profiles can be freely downloaded as ascii files. For each cluster, the coordinates of the gravity centre and a few structural parameters obtained from King or Wilson model fitting are also provided. Further details can be found in Miocchi et al. 2013, ApJ, 774, 151 (a PDF copy is also available at arXiv:1307.6035).
