Recording Times of Acoustical Monitoring (
<
Recording Times
>
- Box)
The recording times of the acoustic monitoring, that means the daily time intervals within which bat
calls will be recorded, can be defined as absolute time intervals or relative to sunrise and sunset.
In case of absolute recording, the daily periods of time within which the recording of bat calls is active
are defined by the two fields <
Recording Period 1
>and <
Recording Period 2
> (see Figure 31). If neither
of both periods is checked, the acoustical monitoring is activated continuously over the whole day.
If bat call recording periods are to be relative to the sun's course, the geographic position of the data
acquisition location has to be entered for the calculation of sunrise and sunset times in the fields
<
Latitude
> and <
Longitude
> (see Figure 32). These coordinates can be determined, for example, on
the Internet using map services such as Google Maps. To specify the number of minutes the bat call
recording is to be started relative to sunrise and sunset, use the two fields <
Delay to Sunset for Start
>
and <
Delay to Sunrise for Stop
>. Hereby, negative values represent the number of minutes before and
positive values the number after sunrise or sunset, respectively.
The resulting daily recording periods are displayed as <
Recording Periods
> for the current day in the
upper right corner (see Figure 31 and Figure 32).
