Map chronic tag shedding parameter

Internal helper called by Setup_Mod_Tagging to construct the TMB/RTMB factor map for ln_conv_tag_shed, the log-scale annual chronic tag shedding rate. This is a scalar parameter.

Usage

do_conv_tag_shed_mapping(input_list, conv_tag_shed_spec)

Arguments

input_list

Named list with $data, $par, and $map sublists. Requires $data$use_conv_fish_tagging.

conv_tag_shed_spec

Character string. One of:

"fix"

Fix ln_conv_tag_shed at its starting value (mapped to NA).

"est"

Estimate ln_conv_tag_shed (mapped to factor level 1).

Value

The input input_list with $map$ln_conv_tag_shed set to a length-1 factor. Active: factor level 1; fixed: NA.

Details

When any fishery fleet has tagging disabled (any(use_conv_fish_tagging == 0)), the parameter is automatically mapped to NA regardless of conv_tag_shed_spec.
