libamtrack (version 0.6.3)

AT.SPC.get: AT.SPC.get

Description

Returns interpolated spc data. Needs list of spc files as input which is obtained by AT.SPC.get.list. TODO: use path.to.files here alternative argument and call AT.SPC.get.list internally.

Usage

AT.SPC.get(spc.list, energy.MeV.u)

Arguments

spc.list

data frame with spc file information as returned by AT.SPC.get.list

energy.MeV.u

requested beam energy, has to be within energy grid covered by spc.list

Value

list with spc data equivalent to those returned by AT.SPC.read.

Examples

## Download data from libamtrack homepage 
##
## To read a simple SPC file, use AT.SPC.read
##

# To get SPC data for arbitrary energy, you first have to make libamtrack aware
## of the appropriate SPC files:
#

#  spc.list <- AT.SPC.get.list(path.to.files,...)  where 'path.to.files'
# should point to spc files

#                                                  OF ONE KIND, i.e. same
# projectile, target, active/passive
#                                                 # but different energies

# N.B.: This routine can also be used to browser spc files and check their
# integrity
##
## Using the returned list, you can get spc data for any energy in between
#

#  spc <- AT.SPC.get(spc.list, energy = ...)       This will can AT.SPC.read
# and AT.SPC.interpolate
#                                                
## returns a list in which the actual data are found in spc$spc
## which can then used in spc related routines, e.g.
## AT.SPC.tapply, AT.SPC.convert.to.DDD, etc.
##
## A spectrum at arbitraty can be obtain by using the data in spc$spc
## with AT.SPC.spectrum.at.depth.g.cm2
