Index
This routine overrides the base class implementation to enable the caches to be cleared for target location.
This means that some conversion methods (in particular those using time in a base class) may not work properly outside the context of a full translation unless they have been subclassed locally.
Date fixups are handled in a super class.
Uses the elevation, azimuth, telescope name, and observation start time headers (ELSTART, AZSTART, TELESCOP, and DATE-OBS headers, respectively) to calculate the base RA.
Returns the RA in degrees.
Uses the elevation, azimuth, telescope name, and observation start time headers (ELSTART, AZSTART, TELESCOP, and DATE-OBS headers, respectively) to calculate the base declination.
Returns the declination in degrees.
Use the average WVM tau measurements.
PRIVATE METHODS
- _calc_coords
-
Function to calculate the coordinates at the start of the observation by using the elevation, azimuth, telescope, and observation start time. Caches the result if it's already been calculated.
Returns an Astro::Coords object.
