ShortID

Declaration:

TSpdc.ShortID (IncludeCaption: boolean): string;

The function ShortID returns a short identifier for the spectral descriptor. This identifier consists of a two- or three-letter code followed by the most important parameters in square brackets. If the parameter IncludeCaption is TRUE the user-defined caption of the descriptor is appended to the identifier. Following are a few examples of such identifiers: TC [1369,1388...1350] ABL [3137...2974] VD [DC033+DC54] GCI [1579,1721...1480] PBL [1723] GC [1824...1637,2]

The code conforms to the description of the spectral descriptors:

Descriptor/ Button	Explanation
ABL	Area: sum of intensities between two reference points with the baseline subtracted.
ALV	Area: sum of all intensities between two reference points; the baseline is defined by the level of the reference point b1.
ARW	Area: the sum of intensities between two reference points; no baseline is subtracted.
BBL	The logarithm of the ratio of two peak areas (with the baseline subtracted) weighted by the area of the second peak.
BRW	The logarithm of the ratio of two peak areas weighted by the area of the second peak; no baseline is subtracted.
CEN	Centroid: the position of the centroid of the spectral line within the boundaries b1 and b2.
COO	Correlation with a positive triangle template peak within the boundaries b1 and b2.
GC	Significant positive correlation (level of significance = 0.01) with a general Gaussian template peak.
GCI	Significant positive correlation (level of significance = 0.01) with an inverse general Gaussian template peak.
PBL	Peak: single intensity at a particular wavelength or mass; the baseline is subtracted.
PLV	Peak: single intensity at a particular wavelength or mass; the baseline is defined by the level of a single reference point b1.
PRW	Raw peak: single unprocessed intensity at a particular wavelength or mass; the baseline is not subtracted.
RBL	Peak ratio: the logarithm of the ratio of two peak intensities at two different wavelengths weighted by the intensity of the second peak.
RLV	Peak ratio: the logarithm of the ratio of two peak intensities at two different wavelengths weighted by the intensity of the second peak.
RRW	Raw peak ratio: the logarithm of the ratio of two peak intensities at two different wavelengths weighted by the intensity of the second peak.
TC	Significant positive correlation (level of significance = 0.01) with a positive triangle template peak, multiplied by the signal area.
TCI	Significant positive correlation (level of significance = 0.01) with an negative triangle template peak, multiplied by the signal area.
VAR	Variance of the first derivative of the spectral line within the boundaries b1 and b2.
