attach_flag
Attachment Flag
Set to 1 if all MDSRs
corresponding to this ADSR
are blank, set to zero
otherwise. This flag will
always be zero because this
ADSR is updated
once per slice or scene.
Therefore, if there are no
MDSRs, this ADSR is not
produced at all.

chirp_flag
Chirp extraction
failed or is of low quality flag
0 = able to reconstruct
all chirps or chirp
reconstruction not requested
(nominal chirp used) AND all
quality measures were
acceptable. 1 = unable to
reconstruct a chirp during
processing and chirp
reconstruction was requested
or the quality is below the
acceptable levels. When
value = 1, (i.e. unable to
reconstruct a chirp during
processing and chirp
reconstruction was requested
or the quality is
below the acceptable
levels), PF-ASAR uses the
nominal range pulse for
processing and a nominal
elevation beam scaling factor.

Data sets
missing flag 0 =

supposed to be in the

data sets (including ADSs)
are missing from the
product which are supposed
to be included under normal
circumstances. When value =
1 (i.e any data sets,
including ADSs, are missing
from the product which are
supposed to be included
under normal circumstances),
which data sets are missing
can be determined by an
examination of the DSDs in
the SPH.
