Chapter 17<br />

Importing <strong>ISO</strong> data products to CIA<br />

CIA provides dedicated FITS handling routines to create the data structures from the data<br />

products distributed on the <strong>ISO</strong> CD-ROMs or retrieved from the IDA. This chapter provides<br />

an overview of their use.<br />

17.1 Importing FITS to CIA data structures<br />

This section describes the CIA routines for importing <strong>ISO</strong> data products to CIA data structures.<br />

Section 17.2 describes routines for importing <strong>ISO</strong> data products, or any extended FITS files for<br />

that matter, to regular IDL structures.<br />

17.1.1 Assigning working directories<br />

To avoid tedious typing, it is useful to assign the path names of the directories you will use in<br />

the calls to the CIA routines to IDL string variables. The directories used in the examples in<br />

this chapter are assigned as follows:<br />

In VMS. . .<br />

product_dir = ’DKA200:[MDELANEY.14300601]’<br />

scd_dir = ’DKA200:[MDELANEY.14300601.scds]’<br />

sad_dir = ’DKA200:[MDELANEY.14300601.sads]’<br />

tdtosn = ’14300601’<br />

. . . and in UNIX. . .<br />

product_dir = ’/home/mdelaney/14300601’<br />

scd_dir = ’/home/mdelaney/14300601/scds’<br />

sad_dir = ’/home/mdelaney/14300601/sads’<br />

tdtosn = ’14300601’<br />

Also, the variable tdtosn is assigned the combined TDT and OSN number.<br />
