7th January 1998 The ~ftp/pub/peter/headers now has two subdirectories cd050 and cd100. The header files up to #50 have been placed in the cd050 subdirectory and the more recent header files in the cd100 subdirectory. The files up to hdsk100 will be placed in the cd100 subdirectory and then a new directory cd150 will be created. As Shai pointed out this will keep everything in order. I have done this for my convenience when transferring the files from the observatory by ftp. cd001050.txt lists the contents of the first 50 cdroms. It is now located with the set of files in the cd050 subdirectory. Peter.
