Following Tom's link to Wikipedia, you can find individual entries for each station, which in turn lists apogee and perigee altitudes:
  • Salyut 1
    Perigee: 200 km (108 nmi)
    Apogee: 222 km (120 nmi)
  • Salyut 3
    Perigee: 219 kilometres (136 mi)
    Apogee: 270 kilometres (170 mi)
  • Salyut 4
    Perigee: 136 mi (219 km)
    Apogee: 168 mi (270 km)
  • Salyut 5
    Perigee: 223 kilometres (120 nmi)
    Apogee: 269 kilometres (145 nmi)
  • Salyut 6
    Perigee: 219 kilometres (136 mi)
    Apogee: 275 kilometres (171 mi)
  • Salyut 7
    Perigee: 219 km (118.25 nmi)
    Apogee: 278 km (150.1 nmi)
  • Mir
    Perigee: 354 km (189 nmi) AMSL
    Apogee:374 km (216 nmi) AMSL

Thank you very much for the quick answers, Tom and Robert!

I was aware of wikipedia, however I do not trust their numbers, since some landing sites given in wikipedia are not correct.

Not to create more confusion, but I believe these were just the initial orbital elements. The stations have heavy drag and drop from orbit quickly. There were numerous reboosts.

Kyra, I fully agree with you. I wanted to provide the readers of my catalogue with typical or average values. In wikipedia and www I only found the initial values which are not representative. I wonder whether anybody ever calculated everage values.
