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. |
