TPSTA is an array of up to 30 station names. One can be 'DEFAULT' which means that the corresponding parameters will be used for stations not explicitly in the list. A station VLBA will match any VLBA stations that are not specified explicitly. Actually it matches any stations with the first four characters ``VLBA''. A station VLA matches any station with the first 3 characters ``VLA'' that is not otherwise specified explicitly. For example, it matches ``VLA1'' and ``VLA27''.
