suffix_bytes
The suffix_bytes element identifies the allocation in bytes of each suffix data value. It is the unit of the dimensions specified by the suffix_items element. In the current build of ISIS, suffix_bytes must always be 4. This means that all suffix items (unlike core items) occupy 4 bytes, even though in some cases the defined suffix data value may be less than 4 bytes in length. -

attribute definition:
mro:replaced_pixel_location
The MRO:REPLACE_PIXEL_LOCATION keyword gives the X,Y,Z locations within a CRISM TRDR at which data values were replaced by interpolating from surrounding pixels, because original data values were affected by cosmic ray hits which increased the DN level above a threshold of several times the read noise in the data. Read noise is approximately 3 14-bit DNs. The X direction is the spatial direction within a single frame of data. The Y direction is the wavelength direction within a single frame of data. The Z direction in the spatial direction built up by accumulating successive frames of data at different times. A cosmic ray hit is manifested by an elevated DN level in a small cluster of adjacent X,Y locations in one or two successive frames in the Z direction. Replacement occurs by interpolating between the adjacent pixels in the XZ spatial directions. The pixel locations are defined as {(X1,Y1,Z1), (X2,Y2,Z2),..., (Xn, Yn,Zn)} where Xn, Yn, and Zn are integer values of X,Y,Z coordinates of replaced pixels. -

msl:input_product_id
The MSL:INPUT_PRODUCT_ID element specifies the product(s) directly used as input to create this product. It may contain either the PRODUCT_ID or the filename of the input products.

For example, a linearized XYZ image would list the left and right linearized input images as well as the disparity file. Contrast this with SOURCE_PRODUCT_ID, which lists only the root EDR source; INPUT_PRODUCT_ID lists the proximate inputs (EDR or RDR) for the process used to create this product. -
