reference_coord_system_name
The REFERENCE_COORD_SYSTEM_NAME element provides the full name of the reference coordinate system for the group in which the keyword occurs. All vectors and positions relating to 3-D space within the enclosing group are expressed using this reference coordinate system. In non-unique coordinate systems (such as 'SITE' for rover missions), which have multiple instances using the same name, REFERENCE_COORD_SYSTEM_INDEX is also required to completely identify the reference coordinate system. Note: For MER, the reference is usually a SITE frame. -

encoding_max_compression_ratio
The encoding_max_compression_ratio element provides the maximum compression ratio applied to the data on board the spacecraft. For Galileo, this keyword is valid only for Integer Cosine Transform (ICT) or Huffman compression. If the image is compressed with ICT this value is the ICT Maximum Compression Ratio, otherwise it is the Huffman Maximum Compression Ratio. -

msl:linearization_mode
The MSL:LINEARIZATION_MODE element specifies the way in which an image has been linearized (see GEOMETRY_PROJECTION_TYPE). It can contain one or two values. The first value specifies what kind of stereo partner was used to linearize the image (the process requires two camera models). A value of 'NOMINAL' means that it was linearized using the nominal stereo partner at the same pointing (whether or not the partner image was actually acquired). 'ACTUAL' means it was linearized using an actual stereo partner image, which may be at a different pointing or rover location (e.g. long-baseline or re-pointed stereo). The product ID of the actual partner used will be in STEREO_PRODUCT_ID. A value of NONE, means that linearization has not been performed. If the value is not present and linearization is on, 'NOMINAL' should be assumed. The second value specifies how the linearized camera model's field of view (FOV) was constructed (corresponding to the 'cahv_fov' parameter in MIPL software; see [reference]). 'MIN' indicates the FOV is the intersection of the two cameras, which means some data is cut off and typically stretched horizontally, but there are no black areas. 'MAX' indicates the FOV is the union of the two cameras, which preserves the edges of the images but typically compresses the image horizontally, and creates black areas. 'LINEAR' uses only the CAHV vectors, which tends to preserve the aspect ratio and scale of the original but both cuts off data and has black areas. 'NONE' means no linearization. If the value is not present and linearization is on, 'MIN' should be assumed. -

start_grating_position
The NIMS instrument has only 17 detectors but takes data in as many as 408 wavelengths by moving a grating across 31 possible physical positions. The start grating position is a logical position relative to the (physical) offset grating position. Together, they control the starting physical grating position in the mode. In fixed grating modes, the start grating position may be commanded to any of the 31 physical positions. In multiple-grating- step modes, it may normally range between zero and one less than the grating increment. For example, in short map mode (with grating increment 4) the start grating position would be between zero and three. See the NIMS instrument paper (R. W. Carlson et al, 'Near-Infrared Mapping Spectrometer Experiment on Galileo', Space Science Reviews 60, 457-502, 1992) for details. -

attribute definition:
suffix_low_instr_sat
The xxx_suffix_low_instr_sat element of a 1-3 dimensional qube object (where xxx is an axis_name of the qube) provides the sequence of low instrument saturation values of the suffix items along the xxx axis. The length of the sequence is specified by the axes element, and its order must correspond to the order of names in the xxx_suffix_names element. In a Standard ISIS Qube, the axis names are restricted to SAMPLE, LINE and BAND. For the BAND axis, for example, the element will be named BAND_SUFFIX_LOW_INSTR_SAT. Each low instrument saturation value identifies the special value whose presence indicates the measuring instrument was saturated at the low end. This value must be algebraically less than the value of the xxx_suffix_valid_minimum element. For Standard ISIS Qubes, a value been chosen by ISIS convention. The general data type of the value is determined by the corresponding xxx_suffix_item_type element. If the latter is integer or unsigned integer, the general data type is integer. If core_item_type is real, the value will be hardware-specific (or rather floating-point-representation-specific) so that it may be specified exactly near the bottom of the allowable range of values. A non-decimal (hexadecimal) general data type is used for this purpose; e.g. 16#FFFDFFFF# for a VAX. -
