Data Labeling and Organization

The data labeling and organization components provide utilities for organizing and labeling data channels, samplers, and channel quantities for fringe fitting operations.

MHO_ChannelLabelerBuilder 

Class	MHO_ChannelLabelerBuilder
Primary Functionality	Builds a channel labeler operator
Key Features	Inherits from MHO_OperatorBuilder Provides Build() method for channel labeler initialization Organizes channels for fringe fitting operations

The MHO_ChannelLabelerBuilder class builds a channel labeler operator that organizes and labels data channels for fringe fitting operations.

MHO_SamplerLabelerBuilder 

Class	MHO_SamplerLabelerBuilder
Primary Functionality	Builds a MHO_SamplerLabeler operator
Key Features	Initializes and builds MHO_SamplerLabeler operator Groups channels by sampler for organization Provides sampler-based channel grouping

The MHO_SamplerLabelerBuilder class builds a sampler labeler operator that groups channels by their associated samplers. This organization is necessary for proper data processing in VLBI systems where multiple channels may be associated with the same sampler hardware (and thus share physical hardware-related delays).

MHO_ChannelUtilities.hh 

Header	MHO_ChannelUtilities.hh
Primary Functionality	Free functions for mapping per-channel control quantities
Key Features	Maps channel names to corresponding values Handles comma-separated or concatenated channel names Logs an error and truncates to the shorter input if channel names and values counts don’t match MapChannelQuantities() function for channel-to-value mapping

The MHO_ChannelUtilities.hh header provides a utility for storing and mapping per-channel control quantities, which is a typical task for fourfit control files. It handles the mapping between channel names and their corresponding values.

The functions can process channel names in various formats (comma-separated or concatenated 1-character names). If the number of channel names and values don’t match, an error is logged and the resulting map is truncated to the shorter of the two inputs.
