Description:
This paper supplements Kerschbaum and Hron (1994), where new JHKL'M
observations of 200 Semiregular variables of types SRa and SRb were
presented with additional 44 near infrared observations and 5
literature data sets.
The total sample was defined in Kerschbaum & Hron (1992, Paper I) by
means of a certain limit in bolometric magnitude. From the sample of
350 objects, 303 now have near infrared (NIR) photometry. In total 339
datasets are available because of some multiple observations. A
detailed analysis of the whole dataset will be presented in a
forthcoming paper.
