Description Usage Arguments Details Value Author(s) See Also Examples

Calculates solar longitudes with respect to the equinox of 2000.0 for given dates.

1	solar.long(date,prec=4)

`date`	character vector or factor specifying dates, given in `"%Y-%m-%d %H:%M:%S"` format (UTC timezone).
`prec`	numeric vector specifying number of decimals of calculated solar longitude (between 2 and 5 decimals). By default it is equal to 4.

The function solar.long represents vectorized version of function sollong. It calculates solar longitudes corresponding to multiple dates.

solar.long returns solar longitude(s), numeric vector with specified number of decimal places.

## calculate solar longitudes corresponding to the middle of time intervals 
## of 2015 Orionids rate data
## first select Orionids from 2015 rate data
rateOri<-filter.shw(rate2015,shw="ORI")

## calculate middle of observing time intervals of 2015 Orionids rate data
midintOri<-midint(rateOri)

## calculate solar longitudes corresponding to the middle of time intervals
solar.long(midintOri)
