V3.0

• Most POLPACK commands have been changed to allow the processing of spectropolarimery data. The main exception to this is the POLKA command, which cannot be used with spectropolarimetry data. Instead, you should align the data manually, and then use POLCAL directly to create Stokes vectors.

• Bugs have been fixed which allow catalogues in STL and TST formats to be used (see SUN/190).

• A bug in POLPLOT has been fixed which caused inappropriate text to be used for the default key heading.

• A new hidden command POLZCONV has been added to transform between calibrated values and pixel values along any spectral channel axis present in a vector catalogue. This command is not intended for interactive use.

• Two new hidden commands POLWRTCL and POLRDCL have been added to transfer catalogue data to and from the polarimetry toolbox within GAIA . These commands are not designed for interactive use.

• POLIMP has a new parameter called ABORT which can be set TRUE to force POLIMP to abort if any input data file cannot be processed.
