 +//In earlier versions of RTS2, this was kept as an extrea field in the database. Now you can use getLastObsTime () call. This returns in seconds time from last observation. If observation was not performed, it returns one year. But this can be easily changed to return nan, so you can use as you wish.//
  
 Additionally, we would like to fix the exposure times for all the targets. What is the easiest way of doing this in rts2? Additionally, we would like to fix the exposure times for all the targets. What is the easiest way of doing this in rts2?
