mk9_find_surface_offset: Find and apply time offset to deck tag data

In sean-rohan/trawllight: Derive apparent optical properties from trawl-mounted light sensors

Find and apply time offset to deck tag data

Description

Calculates correlations between predicted and observed irradiance to calculate an archival tag offset for cases where tag time doesn't match survey time. Iterates through surface irradiance predictions from fishmethods::astrocalc4r based on location data and offset time.

Usage

mk9_find_surface_offset(
  channel = NULL,
  survey,
  vessel,
  cruise,
  try_offsets = seq(-8, 8, 1),
  results_file = NULL
)

Arguments

channel	Oracle connection as an RODBC connection object.
survey	RACE survey code as a character vector.
vessel	RACE vessel code a numeric vector.
cruise	RACE cruise code as a numeric vector.
results_file	Character vector indicating a filepath where offset results should be stored.

Value

Writes time-shifted surface values to corr_deck.csv
