... The scheduling routines assist in creating an observing list (stored in the startable) from scratch or from another list stored on disk, and computing the visibility of the stars in a specific night and array configuration. The date of observation is taken from the variable date , and the array name from the variable systemid . If these are not defined, defaults are used for date (the next night) and for array (NPOI). ... addstar , stars _char Add one or more stars to the startable. ...
