Hi all,

Using information from the Parsamian-Petrosyan paper shared on a CN topic (tip off the hat to Jimi and Steve), I updated the CSOG 2.4 Parsamian Cometary Nebulae edition. It is marked as version 2.4.1.

https://clearskies.eu/csog/downloads/nebulae#parsamian

Using this data, 4 objects were corrected:

- Parsamian 2 is the galaxy PGC17603 in Orion
- Parsamian 10 is the emission nebula Minkowski 1-83 in Orion
- Parsamian 19 is a small nebula west of Van den Bergh 97, in the emission nebula Sharpless 2-302 in Puppis
- Parsamian 20 is the emission nebula Minkowski 1-85 in Puppis

Notes from the Parsamian-Petrosyan paper were added where applicable. Changes will be incorporated into other editions for CSOG 2.5.

If you downloaded the Parsamian edition before, please re-download!

Cheers,


Victor
