Question about output form MARK (Occupancy estimation)

[mspinola]

Dear list members,

I got the following output from an occupancy estimation in MARK.

95% Confidence Interval
Parameter Estimate Standard Error Lower Upper
-------------- -------------- -------------- -------------- --------------
1:p 0.351 0.0435443 0.2717922 0.4410296
2:Psi 0.445 0.1139463 0.2457083 0.6651416
3:Psi 1.000 0.3644528E-04 0.6552500-209 1.0000000

What is the interpretation of the 3:psi (lower limit)?
Thank you very much in advance.
Best,

Manuel Spínola
