PDS_VERSION_ID = PDS3 RECORD_TYPE = STREAM OBJECT = TEXT PUBLICATION_DATE = 2004-10-05 NOTE = "Information on spectral editing masks" END_OBJECT = TEXT END The TES onboard Data Editor aggregates the spectral data from the six detectors, in order to reduce the total amount of data to be downlinked. Data editing is performed according to the Detector and Spectral Masks specified by the sequence. Detector masks are applied prior to spectral masks. Spectral masks are applied to combine data in the spectral domain. The data from each spectral sample may either be selected/rejected, or averaged with the data from adjacent samples. The selection or average option is determined by a bit in the spectral mask itself. The detectors make up an array three detectors wide by two detectors tall. Detectors are numbered from left to right across the array, starting with 1 in the upper left, ending with 6 in the lower right. Each detector has an associated spectral buffer with the same number. There are two spectral masks associated with the data acquired by the central and peripheral detectors respectively. The center mask is used on spectral buffers 2 and 5, while the periphery mask is used on spectral buffers 1,3,4, and 6. At the end of all additions, each data point is divided by the total number of samples used to generate it. In this division any failed detectors are taken into account so that the final numbers are an average of the data from active detectors only. The spectral data is then scanned and shifted appropriately so that the highest value is represented in a 12 bit wide number (sign bit plus 11 bit mantissa). The amount of shifting is the exponent which is also included in the downlinked packet. Data editing is all done "in-place" with the edited data replacing the original values in the spectral buffers. The TES onboard Data Editor keeps track of the final lengths of the six spectral buffers after editing. TES has 19 spectral masks loaded onboard at all times (residing in PROM). The names of these 19 masks are listed below with a brief description of the mask (the bits are defined in specmask.tab); for any averaging mask, the value is returned in the last band of those averaged together. Appendices A.1-4 below contain a coded description, with wavenumber associations, of each mask. Other spectral masks can be designed on the ground and then loaded on board during regular sequence command uploads.

Appendices For each of the following appendices: Bands are associated with the central wavenumber (in cm-1) of detector 2, single scan mode (see DATA/WAVNUMSS.TAB and DATA/WAVNUMDS.TAB for a complete list of central wavenumbers per detector for single scan and double scan modes respectively). Mask numbers correspond to the Masks described above; Masks 19 and 20 have been designed during the mission and loaded onboard for usage by TES. All masks are shown as used during the Mapping phase with ID#1:5 undefined (ID#6 = RAW_RADIANCE[1]); the exceptions are MASK00, which is shown as used throughout the entire mission, and MASK20, which was only used during Aerobraking phases. Coded entry definitions for each band: S = band selected a = band averaged; stored in next available "A" band A = band averaged; average value for all previous "a" bands (if any) stored here (blank) =
