... Searches for Star Formation in Damped Systems . ... The objective was to measure the star-formation rates in these systems. However, no H emission was detected above our limits of Wm -2 , corresponding to star formation rates ( q 0 =0.5). ... For q 0 =0.5 our limits are in conflict with the star formation rates predicted under the assumption that the high- z DLAs are the fully-formed galactic-disk counterparts of today's massive spiral galaxies. ...

... Up: Algorithms . ... Non-linear and non-parametric algorithms for data averaging, smoothing and clipping in the RATAN-600 flexible astronomical data processing system are proposed. Algorithms are based on robust methods and non-linear filters using an iterative approach to smoothing and clipping. ... The history of algorithms, based on the robust methods and non-linear filters using an iterative approach to smoothing and clipping, began twelve years ago in the data reduction at the RATAN-600. ...
