A software update was released today that includes a bug fix and improvements to the user input validation process.
The bug that was causing the name resolver argument to be ignored has been fixed. Due to the bug all positions were being processed using the default setting which checks the SIMBAD service before checking the NED service. Now positions are being processed as specified by the user. We apologize if this has caused any confusion.
We have put in place more stringent input validation procedures to prevent processing of malicious data. In some cases incorrect but innocuous input that was previously accepted may result in the termination of a query. We hope that our error messages will provide enough information for the user to be able to correct the input. If not please let us know.
