Description:
In this paper we present the catalog of new Mira-type and SR+L
variable stars in the Northern Sky Variability Survey (NSVS) database,
found after complementing the original NSVS object tables with a
number of additional parameters. By extending the amount of criteria
search queries can take advantage of and filtering known objects out,
it became convenient to apply better constrained filters to search new
variable star candidates. As an example of presented approach, the
quest for red variables has resulted in 78 Mira-type and 717 SR+L
stars found that have no identification in General Catalogue of
Variable Stars, SIMBAD and VSX databases. Most likely the stars
presented are new discoveries. The classification of these stars is
based on the near-infrared colors from Two Micron All Sky Survey
(2MASS) photometry, amplitude and period with the accuracy of the
classification given ∼90%, estimated basing on the current GCVS
classification scheme.

the standard deviation.
Note (2): Predicted class as follows:
M = Mira-type variable
M: = suspected Mira-type variable
SR+L = Semi-regular and long variable
