First it provides magnetic plans of sites unpublished before. For the sites Horný Ohaj, parts of Čifare, Nevidzany, parts of Úľany nad Zitavou and Vlkas, a handcart with 6 Foerster fluxgate gradiometers in a 0.5 m spacing was used. Each of these magnetometers consists of two sensors which are vertically positioned in a distance of 0.65 m and the difference in their signals is measured. For Maňa, Telince and parts of Úľany nad Zitavou, a handcart with 9 SENSYS-Foerster fluxgate gradiometers, also spaced 0.5 m apart was employed. Finally, the site Vráble 'Drakovo' was measured with a 16-channel system (SENSYS MAGNETO®-MX ARCH). In all three cases, the setup was accompanied with a DGPS and a monitoring laptop.
Second,it contains a PostgreSQL-dump (vers. 9.3.25) as txt-file with the relevant tables and views to reproduce the computation of house orientations. For further reference, the main tables (polygons_mf, polygons_nms, polygons_wm) also exist in a version as plaintext WKT (polygons_mf_as_text, polygons_nms_as_text, polygons_wm_as_text).

No full textMeasurement of elastic J / psi photoproduction at HERA
No full textThe reaction a p --> J/psi p has been studied in epsilon p interactions using the ZEUS detector at HERA. The cross section for elastic J/psi photoproduction has been measured as a function of the photon-proton centre of mass energy W in the range 40 J/psi p), is observed to rise steeply with W. A fit to the data presented in this paper to determine the parameter delta in the form sigma(ap-->J/psi p) proportional to W-delta yields the value delta=0.92+/-0.14+/-0.10. The differential cross section d sigma/d\t\ is presented over the range \t\ < 1.0 GEV(2) where t is the square of the four-momentum exchanged at the proton vertex. d sigma/d\t\ falls exponentially with a slope parameter of 4.6+/-0.4(-0.6)(+0.4) GEV(-2). The measured decay angular distrubitions are consistent with 8-channel helicity conservation

No full textMeasurement of the cross-section for the reaction gamma p ---> J / psi p with the ZEUS detector at HERA
No full textThis paper reports the cross section measurements for the process ep --> e J/psi p for Q(2) < 4 GeV2 at root s = 296 GeV, based on an integrated luminosity of about 0.5 pb(-1), using the ZEUS detector. The J/psi was detected in its e(+)e(-) and mu(+)mu(-) decay modes. The photoproduction cross section was measured to be 52(-12)(+7) +/- 10 nb at an average gamma p centre of mass energy of 67 GeV and 71(-20)(+13) +/- 12 nb at 114 GeV. The significant rise of the cross section compared to lower energy measurements is not in agreement with VDM models, but can be described by QCD inspired models if a rise in the gluon momentum density at low x in the proton is assumed
