**** Current status:    
**** Full northern POSS1 to approximately 20 degrees from Galactic   
**** plane is available.  First 4 equatorial dec strips of southern UKST   
**** (ie. 0, -5, -10, -15) to 30 degrees from Galactic plane also available   
**** - though still many missing fields in this region due to lack of R 
**** survey plates. Several of the SES UKST strips are also now included 
**** down to -65 degrees dec with the same caveat as above.

**** To do a list create a script with command line arguments as above.
