necst_msgs.srv.ScanBlockCommand

Request a continuous scan block composed of multiple control sections.

Shared target/reference context: - Use name for a named moving/trackable target. - Otherwise use lon / lat / frame for the block reference. - offset_lon / offset_lat / offset_frame are block-wide offsets applied after the target/reference is realized.

Shared numerical context: - unit is the angular unit for all section coordinates and speeds. - cos_correction has the same semantics as in CoordinateCommand. - direct_mode and obsfreq are forwarded to the control-side coordinate conversion path in the same way as existing point/scan commands.

Section list: - sections is an ordered array. The control side executes them as one execution id. - Section geometry is defined semantically; actual section start timestamps are owned by the control side, not by this request.

Fields

• lon (float64[<=1]) -- Reference longitude, if not using name.
• lat (float64[<=1]) -- Reference latitude, if not using name.
• frame (string) -- Reference frame for lon / lat.
• offset_lon (float64[<=2]) -- Block-wide longitude offset.
• offset_lat (float64[<=2]) -- Block-wide latitude offset.
• offset_frame (string) -- Frame of block-wide offsets.
• cos_correction (bool) -- Apply 1/cos(lat) correction to longitude offsets.
• unit (string) -- Angular unit used by all sections.
• name (string) -- Named target. Empty string if not used.
• direct_mode (bool) -- Skip pointing error / atmosphere conversion if true.
• obsfreq (float64) -- Observation frequency [GHz]. 0.0 => use config default.
• sections (ScanBlockSection[]) --
• --
• id (string<=64) -- Identifier of the accepted control execution.
