| DSSbitType | error |
| | Column must be an integer for bit mask filters
|
| BlockSpec | error |
| | File/block specification is not in a format supported by the data subspace.
The deprecated forms using [] or + cannot be used with the data subspace.
|
| DssRefClash | error |
| | The filter references different blocks (referring
to different block filters) with the same name. The data subspace cannot
be written.
|
| DssBlockClash | warning |
| | Name clash while writing Data Subspace. Block already
exists in output data set.
corrective action: The block is renamed.
|
| NoFilter | error |
| | Filter not found in data subspace component.
|
| NoRange | error |
| | No range information available for this filter type.
|
| DSextentType | error |
| | The filter is not of a type for which a determination
of the extent is supported (eg. a mask filter)
|
| DSextentGTI | error |
| | The argument of the extent command does not correspond to
the name of the GTI filter being queried.
|
| DSextentRange | error |
| | The argument of the extent command does not correspond to
the name of the Range filter being queried.
|
| DSextentRegion | error |
| | The argument of the extent command does not correspond to
the name of one of the components of the Region filter.
|
| NoMask | error |
| | No bit mask information available for this filter type.
|
| NoRegion | error |
| | No region information available for this filter type.
|
| NoBlock | error |
| | No block information available for this filter type.
|
| BlockTypeGti | error |
| | Block type is not compatible with the gti filter type.
|
| BlockTypeMask | error |
| | Block type is not compatible with the mask filter type.
|
| DSSblockType | error |
| | The filter type for the specified block could not be determined.
|
| MaskType | error |
| | Mask array is not of a supported data type.
|
| DSStype | error |
| | Incompatible data types for DSS and column specifications.
|
| BlockTypeRange | error |
| | Block type is not compatible with the range filter type.
|
| RangeType | error |
| | Columns are not of a supported data type for a range specification.
|
| BlockTypeRegion | error |
| | Block type is not compatible with the region filter type.
|
| ColumnClash | error |
| | Data subspace filter name and column name are not consistent.
Cannot write data subspace.
|
| BadRegionFilter | error |
| | A data subspace filter with a region specification has been
found. This type of filter is not supported.
|
| BitVol | warning |
| | Cannot calculate volume for
a bit mask filter.
corrective action: Zero volume returned for this filter type.
|
| RangeVol | warning |
| | Cannot calculate volume of
a range specification with only one limit.
corrective action: Zero volume is returned for this filter.
|
| DSStypeTruncate | warning |
| | Real-valued ranges are used for an integer-valued column.
corrective action: Real-valued ranges are truncated to integers.
|
| DssSyntaxError | error |
| | The parser was not able to parse the selection expression so as
to convert it to a data subspace specification.
|
| ArithmeticException | error |
| | An illegal arithmetic operation was specified in the selection
expression.
|
| MaskSpecOffset | error |
| | A mask filter was specified with a non-zero offset. The data subspace
is only able to store masks with a zero offset.
|
| DssNameMismatch | error |
| | Name of coordinate axes in region filter do not match that of
preceding filter in same component. See section on ``Tips and Grouping of Region Functions''
to find out how to avoid this error.
|
| BitMaskTesting | error |
| | Bit mask filter must be tested against ``== 0''. This syntax, along with
the equivalent syntax ``!(mask!==0)'', are the only two that are supported.
|
| DssFitsWrite | warning |
| | The data
subspace indexing has become to large to fit into keywords of the from nDSVALn (keywords can
be on more than 8 characters). Thus no filter information can be written to the FITS header
for the filter in question.
corrective action: No data subspace information is written for the given filter.
