... This command selects one subframe from the original frame and generates an artificial image identical to the primitive but with the quoted window added at given positions. If this window contains one stellar image, one is able to determine, through a new ROMAFOT session, the ability of the procedure to detect an object and the general reproducibility of the photometry. A catalogue, similar to that created by FIND/ROMAFOT , is generated by ADDSTAR/ROMAFOT . ...

... The analysis and reduction of the STIS flanking fields proceeded in similar fashion as for the imaging of the Main STIS Field. ... The DARK calibration reference file used in the CALSTIS data reduction steps was constructed using a 'delta-dark' image appropriate for the epoch of the flanking field observations. ...

... Consequently, it is inappropriate to expand and in ordinary spherical harmonics. The proper expansion expresses both and simultaneously in terms of a particular order of generalized spherical harmonics. ... Generalized spherical harmonics start at , and for each , . ... Generalized spherical harmonics obey a sum rule analogous to a familiar one for ordinary spherical harmonics, but it includes an explicit phase factor which depends on the orientation of the two lines of sight. ...

... What follows is the list of talks at the IUM general seminar "Globus" delivered during fall semester, 2005. ... In the 1960s, H. Steinhaus asked whether every closed curve in space has a pair of parallel tangent lines; a curve without parallel tangents is called a skew loop. ... A skew brane is a multidimensional analog of a skew loop: it is a codimension 2 submanifold without parallel tangent spaces. ... There exist totally skew n-dimensional spheres in 3n+2-space, and in 3n+1-space if n is odd. ...
