CHET – Chart Error Tracking Tool
CHET was created to track of all reported issues with AAVSO variable star charts and sequences and the chart and sequence team’s progress in addressing those issues. Information reported to CHET by observers is used to evaluate and prioritize the work done by the charts and sequences team. When the team makes revisions or corrections, CHET automatically sends an email notification to the observer who reported the issue. The improvement in the quality of charts and sequences, and the speed with which new sequences are created for new transient objects, in the last ten years, is nothing short of amazing.
This is just one example of the tools and programs the AAVSO provides to its members, observers and the astronomical community. Please help support these services by contributing to this year's Annual Campaign.
