The original files with the data were in different formats. ... Such files were named "standard data files" and linked to the database. They can be easily transformed to any desirable format by a code. Here we present two simple computer programs of this kind. ... When running the code, you can specify columns in the output file: wavelength, energy (eV) or wavenumber (cm -1 ) as the first column, and complex refractive index or dielectric function as the second and third columns. ...

Computing dates when an LST is at night time . The program nighttime (written by Mike Nolan and available on AO computers - e.g., mofongo.naic.edu) computes the dates when a particular LST occurs at night time at Arecibo. ... The nighttime program prints out the word "Night" on the first date when the LSTs fall entirely at night, and "Day" on the first date when the LSTs sometimes cross into daytime. Rise/Set is defined to be when the center of the sun is 0.833 degrees below the horizon.) ...

Numbering Procedures for APO 2.5m and 3.5m Drawings and Engineering/Drafting Documents . ... Document part numbers are to consist of a 7 character long "base numbe,r" which is coded to provide information about the part's intended first use. The part number becomes complete and unique only with the addition of a revision number. ... Example of a "base number": 25CSA01 . ... PART NUMBER CONVENTION . ... For Example: . ...

The first persistent Web agent that we have created on Actor Prolog is a program that collects information about research groups that develop Prolog and projects in the field of logic programming. The agent looks through a given list of Web sites and calculates some attributes of the sites: the date of recent modification, total size, the number of figures, the number of outside links, the number of error links, the number of given keywords, etc. ... http://www.cplire.ru/Lab144/space/prolog.html . ...

A different target must be defined whenever different coordinates or a different target description are required. ... For example, if you were to take spectra at three different locations in the Crab Nebula, each point must have its own target number, name, and coordinates, such as CRAB1, CRAB2, and CRAB3. ...

The aim of this assignment is to teach you how to carry out a very common programming task: reading in a bunch of data from a text file, doing something with it then writing the results out again. ... The goal of the assignment is to write a computer program which will select this sample for you. You will pick the micro-quasars to observe from a rather large catalogue, which can be found here: The catalogue is an ASCII (text) file - you can inspect it with a normal text editor. ...

. A file is a collection of letters, numbers and special characters: it may be a program, a database, a dissertation, a reading list, a simple letter etc. Sometimes you may import a file from elsewhere, for example from another computer. If you want to enter your own text or data, you will start by creating a file. Whether you copied a file from elsewhere or created your own, you will need to return to it later in order to edit its contents.
