External Resources
The following FTP sites make the Tycho-2 catalog available as 19 gzipped files. After retrieving them and the index.dat file, combine the gzipped files into catalog.dat. The resulting files will differ from the files on the CD-ROM in that they will end lines with only a linefeed, while the CD-ROM version for which WCSTools software was written terminates lines with a carriage return and a linefeed. Add the carriage returns back to the files using the unix2dos -ascii command.
Put the catalog.dat and index.dat files in a subdirectory data/ to the directory pointed to by the TY2_PATH environment parameter or the ty2cd variable in libwcs/ty2read.c.

Famous quotes containing the words external and/or resources:
“For those parents from lower-class and minority communities ... [who] have had minimal experience in negotiating dominant, external institutions or have had negative and hostile contact with social service agencies, their initial approaches to the school are often overwhelming and difficult. Not only does the school feel like an alien environment with incomprehensible norms and structures, but the families often do not feel entitled to make demands or force disagreements.”
—Sara Lawrence Lightfoot (20th century)
“In Western Europe people perish from the congestion and stifling closeness, but with us it is from the spaciousness.... The expanses are so great that the little man hasn’t the resources to orient himself.... This is what I think about Russian suicides.”
—Anton Pavlovich Chekhov (1860–1904)
