Such images are not included because they were not received on Earth or they were not recoverable from any available magnetic tape media. The data fields in the LOSTIMAG Table contain the planned values for such images. The ODL object descriptions in this label file describe the data fields in each row of the LOSTIMAG Table. The table contains one row for each unrecovered image file. This is a cumulative list that includes unrecovered images from all of the CD-ROMs in the Viking Orbiter image series so far. The table is formatted so that it may be read directly into many data management systems on various host computers. All fields (columns) are separated by commas, and character fields are enclosed in double quotation marks. Each record consists of 396 bytes, with a carriage return/line feed sequence in bytes 395 and 396. This allows the table to be treated as a fixed length record file on hosts that support this file type and as a normal text file on other hosts."
