| Abstract: |
The data model library (DM), a Chandra X-ray data analysis software (CIAO)
package (Fruscione et al. 2006), facilitates a wide range of "on-the-fly" data manipulation
capabilities such as copy, merge, bin and filtering. We have recently extended
these capabilities to include pixel mask filtering.
Pixel mask filtering is integrated into the DM region filtering syntax and logic,
and thus complements the conventional geometric shape filtering.
This integration allows for the standard operations on combining masks and shapes
such as include, exclude, intersection, and union.
The mask image is stored as a data block in the output file, and
referenced by the region filter string in the data subspace.We will
highlight the usage of pixel mask filtering in the CIAO software and discuss the
unique features associated with the mask filtering. |
