Charts and Sequences Update January 2012

There are over 100 new and revised charts and sequences since the last update in November. Many of these are for stars in the newly formed YSO Section Program, southern stars with new photometry from APASS and campaign targets. The rest are revisions based on issues reported to CHET and requests for new sequences from our observers.
