Solid State Imaging Raw Experiment Data Record Software Interface Specification 3-2 Table 3-1. Programs Affecting SSI Data - Continued Program Input Output Description GLLFILLIN UDR REDR REDR REDR Fills in missing image lines due to data outage or data compression errors. EDR EDR GLLMVLN UDR UDR Shifts lines downward due to the CDS line dropout problem and bottom partial records. GLLTELEMPROC telemetry data UDR Generates UDR files. SSIMERGE2 UDR UDR Merges two or more images to produce another image with less missing data. UNMOSAIC UDR UDR Accepts an on-chip mosaicked (OCM) UDR as input and outputs each mosaic element as a separate UDR. 3.2 Synchronization Considerations N/A 3.3 Input/Output Protocols, Calling Sequences N/A 3.4 Utility Programs GEDRLIST displays binary header and prefix labels for verification purposes. LABEL-LIST displays VICAR label information for verification purposes. LABLIST displays VICAR label information in a compact format for verification purposes.
Solid State Imaging Raw Experiment Data Record Software Interface Specification 4–1 4 DETAILED INTERFACE SPECIFICATIONS 4.1 Structure and Organization Overview Each REDR file will begin with a VICAR label, followed by the REDR telemetry header and a number of REDR bad-data value headers followed by REDR line records. Each line record will contain 200 bytes of line header information plus the pixel data (8 bits/pixel). See figure 4-1 for a diagram of the REDR file. VICAR Label Binary Header (Telemetry Header Record & Bad-Data Value Header Records) Body Binary Prefix (Line Header) Image Data (pixels) Figure 4-1. REDR/EDR File Diagram All records have a fixed 1000-byte length within each REDR file. All formats have 1000-byte records. Note: Summation mode images occupy the first 400 lines and 400 samples of the 800 line by 800 sample REDR and UDR. For all REDRs (including summation mode), the telemetry header is split into two physical records. The first 1000 bytes are placed in the first physical record after the VICAR label (the VICAR label may span more than one physical record), and the last 800 bytes are placed in the next physical record. The last 200 bytes of this record are zero filled. There will be a one-to-one correspondence between line records and image lines (Excluding the header records, line record n will contain the data for image line n). Missing data lines can be artificially filled by the GLLFILLIN program using interpolation. Missing ICT or Huffman compressed SSI packets will not be
