IUESIPS produces data in Guest Observer (GO) format. These files are variable
length binary files consisting of a label followed by data records. The file
names vary depending on the source of the data. For example, archival data
stored at the National Space Sciences Data Center (NSSDC) is in GO format with
names as follows:
The Data Analysis Center software has its own ``RDAF'' format, consisting of
fixed length record files. The label resides in its own file (with .LAB
extension), and the data in a separate file (with .DAT extension), with other
modifications. The filename is made up of three parts:
The valid types are given in Table 1.2.
Except for data processed in the first couple years after launch, and in data retrieved from the now extinct ``IBM'' database (see Section 2.2) an aperture abbreviation is almost always included in the ``type''.
|R||RAW||Raw image file.|
|P||PI||Photometrically corrected image file.|
|Sap||ELBLn||Spatially resolved low dispersion file.|
|Hap||MEHIn||High-dispersion extracted spectrum file.|
|Lap||MELOn||Low-dispersion extracted spectrum file.|
|F||FESi||Fine Error Sensor (i = 1 or 2) image file.|
For RDAF format data, this filename (without the .DAT or .LAB extensions) will constitute the imaget. For the most part you need not specify the extension because the software automatically selects the correct extension.
There is another format, ``GO-Split'' format. Basically, this is GO format with the label and data in separate files. (RDAF format is different from GO format in other ways.) The Data Analysis Center does not support GO-Split format. However, it is available from the archives, and unfortunately the naming convention is similar to that for RDAF format. If you plan to use our software, don't request this format.
