1. Determine H0 using a SQL query to LEDA
... SQL | ... Tutorial: determine H0 using SQL queries to LEDA . ... We select in the database all galaxies with known velocity and magnitude and similar to a given template for which we know the distance, the magnitude and the radial velocity. ... We simply have to choose a property which does not depend on the distance, as for example the rotation velocity ( log(vrot) ) and select the galaxies having log(vrot) in a very narrow range around the value for the template galaxy. ... leda@univ-lyon1.fr ...

11. Fabry-Perot Interferometer: Data cubes
Fabry-Perot data cubes. Introduction: what is "data cubes"? Observations with the IFP consist of successive acquisition of a few dozen images of interference rings from the object (or from a calibration lamp) when changing the optical path between the flat-parallel plates. The radius of the rings is a function of wavelength and gap between the plates of the interferometer. ... Its interference rings of Ne line which use for phase calibration (convert object data to wavelength-scale). ...

14. Source matching
... In order to produce the merged source-list from all the individual input source-list files, omsrclistcomb first produces a list of all the input sources sorted into order of decreasing source significance. To decrease the CPU time taken in the matching process, the distance (d) between two sources is computed from their equatorial-rectangulr coordinates (x, y and z), using the following formulae: . The equatorial coordinates are only computed once. ...
