Next: The Optopus session Up: Using the Optopus Previous: Using the Optopus . The commands in the Optopus package have to initialised by setting the Optopus context with the MIDAS command SET/CONTEXT OPTOPUS . ... Since almost all commands in the package work, both in input and in output, on MIDAS tables, another important task of the user at the start of an Optopus session will be to create a MIDAS table from the ASCII file where the data about the objects to be observed are being kept. ...

The sort command is a simple database tool. It allows you to specify the field to be sorted on and the type of sort to be carried out on it. sort filename . Lines are sorted into the following order: lines starting with numbers come first, followed by lines starting with upper-case letters, which are followed by lines starting with lower-case letters and finally symbols such as % and ! ... Saving the results of a sort to a file . Checking if a file has been sorted . ...

In this chapter we will consider an example of visual expert system written on the Actor Prolog language. ... There are a lot of methods of oil field bed stimulation that increase output of the oil production: thermal, physical-chemical, gas, microbiological, and others. ... Fig. ...

Gas methods. ...

... Definition lists : the DL , DT , and DD elements . ... Definitions. ... An ordered list, created using the OL element, should contain information where order should be emphasized, as in a recipe: . ... Definition lists, created using the DL element, generally consist of a series of term/definition pairs (although definition lists may have other applications). ... For example, using CSS, one may specify that the style of numbers for list elements in a numbered list should be lowercase roman numerals....

Many entry fields permit sexagesimal entry (h:m:s.s or :':"). ... Sexagesimal entry is flexible in that you can specify one to three fields, as you desire. ... Position entry widgets assume that a single field is decimal hours or degrees (h.h or . ... You may specify one to three fields: . ... Note: sexagesimal offsets and durations are entered in the same fashion, but a single field is decimal arc-seconds or seconds ('.' or s.s) and two fields are (arc) minutes and seconds (':"." or m:s.s). ...

... Number of Strips: This is the total number of strips to be covered for the map. The map size (in declination), is then (Number of strips 1) (Dec step) + (Beam size). If you wish to do a complete map, you must have (Number of strips) = 2 INT[(Dec Offset)/(Dec Step)+0.5] +1 . ... If you wish to do a complete map, you must have (Number of strips) = 2 INT[(Dec Offset)/(Dec Step)+0.5] +1 the declination of your first strip will be ([object Dec] + [Dec Offset]). ...

... Observation codes for VSOP General Observing Time observations have the form . ... The first letter indicates which AO period the observation was proposed in: the letter `v' indicates the first AO period, and the letter `w' indicates the second and third AO periods. The three digits indicate the proposal number. ... For proposals with more than 26 experiments (see next item), 300 is added to the proposal code for the 27th and subsequent experiments. ...

... Shock is a non-linear plasma wave generated by plasma flow (Burgess, 1995). ... Shocks are thus places where plasma and field go through dramatic changes in density, temperature, field strength, and/or flow speed. If there is no plasma flow through the surface (Un <> 0) or there is no dissipation and compression across it, we talk about discontinuity only, not shock. ... Contact discontinuity . ... Plasma pressure and field strength increase at shock; magnetic field bends away from normal . ...

... The absolute Galois group of Q, denoted Gal(\bar{Q}/Q) in the sequel, is a fundamental object in arithmetics since it carries a lot of informations about number fields. ... A classical way to study this group is to use p-adic numbers. ... firstly, we will explain the classical d vissage of Gal(\bar{Q_p}/Q_p) based on ramification theory; as a corollary, we will deduce that any finite extension of Q_p is resoluble; . ...

... INTRODUCTION This data set contains fluxes and pitch angles (relative to measured magnetic field) of protons and electrons as measured in the lower half of the energy steps of the electrostatic analyzers, that is, at "<10 ev," 40 eV and 0.76 keV, 60 eV and 1.2 keV, and 100 eV and 1.8 keV. ... In the data files the values of the particle number flux is given in the data columns in units: particles per square cm per second per steradian per keV. ... FILES AND FORMAT DESCRIPTION 3.1. ...

... The first step to improve the FORS calibration is therefore to obtain data to allow a computation of the illumination correction across the field. ... Another limitation on the calibration accuracy has been the brightness of the Landolt standards which have forced the use of extremely short exposures introducing small but non-negligible shutter-time errors and also resulting in a very small number of useful standards per frame. ...

... This program was created for correlating chosen regions in the series of fts images. ... Chosen regions' . ... In this section the program counts the integral for each region of the grid for each image. ... As a matter of fact, the integral is total brightness of the region and it is counted by 'int_tabulated' IDL function. ... In addition, the program will show the count of the regions which correlate with the corresponding region (the brighter region means the bigger count) and its contour. ...

... This appartus will drop a mass from different heights. When the mass strikes the ground, some percentage of its original energy will be absorbed by the ground. ... The percentage of the energy which is absorbed by the surface on each "bounce" (EAS) . ... The impact velocity of the object will also be given at each bounce. ...
