CHAPTER 7 SAD TO FITS TRANSFER The program SADFITS transfers an image from the SAD disk file format to the FITS tape file format. To run the program: $MOUNT/FOREIGN MTXX: $SADFITS The program then asks 'Is tape to be initialized (Y or N)?' If the answer is 'Y' the data is written starting at the beginning of tape (any data on the tape is overwritten). If the answer is 'N' the tape is positioned at the end-of-tape (two file marks) and the data written there. The program then prompts for the name of the input file: ' SAD file name (
to open a new file):' Transferring maps from the file is continued until a map number of zero is requested, when the program asks for a new file name.
