Purpose

Take one or more sets of 4 polarimetry images at PLANGLE
values of 0, 45, 22.5, and 67.5 deg. Turn on disk writing and
returns this setting to its original state at completion of the
script.

Usage

pol_acqr [n]

Arguments

n = number of exposure SETS to acquire

Output

Transcript written to STDOUT.

Restrictions

This should not be run at the same time as the pol_acqr
script, as the two will try to move the same stage and hence
conflict.

Exit values

0 = normal completion
1 = wrong number of arguments

Example

1) Acquire 5 sets of polarimetry data with the blue CCD

pol_acqr 5
