Detailed Description

Intended use:

Internal

 <h3>Review Status</h3><dl><dt>Date Reviewed:<dd>yyyy/mm/dd<dt>Test programs:<dd>tGBTSampler</dl> 

Prerequisite

• GBT FITS files.
• GBT ACS FITS file.
• GBTBackendTable

Etymology

This holds information typically found in the SAMPLER table of the GBT backend FITS files.

Motivation

It is useful to provide a common interface to access the information in the sampler table. In addition, since only the GBT ACS follows the full convention and provides a complete sampler table, it is useful to make the other backends appear as if they had this table so that downstream code need not know about the differences.

Member Function Documentation

const String& GBTSampler::bankA

(

uInt

whichRow

)

const [inline]

BANK_A for a given row.

For ACS, returns value in BANK_A column SP receiver row is now correctly translated to BANK_A values for Sqr/Cross mode and Square modes. For the DCR, returns value of INPBANK keyword.

Definition at line 93 of file GBTSampler.h.

References itsBankA.

const String& GBTSampler::bankB

(

uInt

whichRow

)

const [inline]

BANK_B for a given row.

For ACS, returns value in BANK_B column. SP receiver row is now correctly translated to BANK_B values for Sqr/Cross mode and Square modes. For DCR bankB==bankA.

Definition at line 100 of file GBTSampler.h.

References itsBankB.

Bool GBTSampler::hasCross

(

)

const [inline]

Does this SAMPLER have any cross-polarization data.

For ACS, this returns True if POLARIZE=="CROSS" For SpectralProcessor this returns true in SquareCross mode. For DCR data this always returns False.

Definition at line 120 of file GBTSampler.h.

References itsHasCross.

uInt GBTSampler::nchan

(

uInt

whichRow

)

const [inline]

Return the number of channels for this row of the sampler table.

Definition at line 123 of file GBTSampler.h.

References itsNchan.

uInt GBTSampler::nrows

(

)

const [inline]

The number of rows (samplers) present.

Definition at line 86 of file GBTSampler.h.

References itsBankA.

GBTSampler& GBTSampler::operator=

(

const GBTSampler &

other

)

Assignment operator, uses copy semantics.

Int GBTSampler::portA

(

uInt

whichRow

)

const [inline]

PORT_A for a given row.

For ACS, returns value in PORT_A column. SP receiver row is now correctly translated to PORT_A values for Sqr/Cross mode and Square modes. For DCR, this is the value of CHANNELID + 1.

Definition at line 107 of file GBTSampler.h.

References itsPortA.

Int GBTSampler::portB

(

uInt

whichRow

)

const [inline]

PORT_B for a given row.

For ACS, returns value in PORT_B column. SP receiver row is now correctly translated to PORT_B values for Sqr/Cross mode and Square modes. For DCR portB==portA.
